The Complete Guide: Hypothesis Testing in Excel

In statistics, a hypothesis test is used to test some assumption about a population parameter .

There are many different types of hypothesis tests you can perform depending on the type of data you’re working with and the goal of your analysis.

This tutorial explains how to perform the following types of hypothesis tests in Excel:

  • One sample t-test
  • Two sample t-test
  • Paired samples t-test
  • One proportion z-test
  • Two proportion z-test

Let’s jump in!

Example 1: One Sample t-test in Excel

A one sample t-test is used to test whether or not the mean of a population is equal to some value.

For example, suppose a botanist wants to know if the mean height of a certain species of plant is equal to 15 inches.

To test this, she collects a random sample of 12 plants and records each of their heights in inches.

She would write the hypotheses for this particular one sample t-test as follows:

  • H 0 :  µ = 15
  • H A :  µ ≠15

Refer to this tutorial for a step-by-step explanation of how to perform this hypothesis test in Excel.

Example 2: Two Sample t-test in Excel

A two sample t-test is used to test whether or not the means of two populations are equal.

For example, suppose researchers want to know whether or not two different species of plants have the same mean height.

To test this, they collect a random sample of 20 plants from each species and measure their heights.

The researchers would write the hypotheses for this particular two sample t-test as follows:

  • H 0 :  µ 1 = µ 2
  • H A :  µ 1 ≠ µ 2

Example 3: Paired Samples t-test in Excel

A paired samples t-test is used to compare the means of two samples when each observation in one sample can be paired with an observation in the other sample.

For example, suppose we want to know whether a certain study program significantly impacts student performance on a particular exam.

To test this, we have 20 students in a class take a pre-test. Then, we have each of the students participate in the study program for two weeks. Then, the students retake a post-test of similar difficulty.

We would write the hypotheses for this particular two sample t-test as follows:

  • H 0 :  µ pre = µ post
  • H A :  µ pre ≠ µ post

Example 4: One Proportion z-test in Excel

A  one proportion z-test  is used to compare an observed proportion to a theoretical one.

For example, suppose a phone company claims that 90% of its customers are satisfied with their service.

To test this claim, an independent researcher gathered a simple random sample of 200 customers and asked them if they are satisfied with their service.

  • H 0 : p = 0.90
  • H A : p ≠ 0.90

Example 5: Two Proportion z-test in Excel

A two proportion z-test is used to test for a difference between two population proportions.

For example, suppose a s uperintendent of a school district claims that the percentage of students who prefer chocolate milk over regular milk in school cafeterias is the same for school 1 and school 2.

To test this claim, an independent researcher obtains a simple random sample of 100 students from each school and surveys them about their preferences.

  • H 0 : p 1 = p 2
  • H A : p 1  ≠ p 2

Excel Tutorial: How To Do A Hypothesis Test In Excel

Introduction.

Welcome to our Excel tutorial on how to conduct a hypothesis test using Excel. Hypothesis testing is a crucial component of statistical analysis, allowing us to make inferences about a population based on sample data. Using Excel for hypothesis testing offers several advantages, including its familiarity, ease of use, and the ability to perform complex statistical calculations with just a few clicks.

Key Takeaways

  • Hypothesis testing is essential for making inferences about a population based on sample data.
  • Using Excel for hypothesis testing offers familiarity, ease of use, and the ability to perform complex statistical calculations.
  • Organizing and formatting data correctly in Excel is crucial for hypothesis testing.
  • Understanding the different types of hypothesis tests and selecting the appropriate test is important for accurate analysis.
  • Interpreting the results of the hypothesis test and avoiding common mistakes is essential for making valid conclusions.

Setting up the data in Excel

When conducting a hypothesis test in Excel, it is crucial to properly organize and format your data in a spreadsheet. This will ensure accurate and reliable results.

  • Start by opening a new Excel spreadsheet and entering your raw data into the cells. It is important to have a clear understanding of the variables you are working with and how they relate to each other.
  • Label each column with a clear and descriptive header to identify the variables being tested. This will help you keep track of the data and make it easier to analyze.
  • Arrange the data in a logical and organized manner, such as grouping similar data together and using separate columns for different variables.
  • Check that the data is formatted correctly, especially if it includes dates, currency, or percentages. Use the appropriate formatting options in Excel to ensure the data is displayed accurately.
  • Remove any unnecessary formatting, such as extra spaces or special characters, to avoid errors in the analysis process.
  • Double-check for any missing or erroneous data entries, and make sure that the data is complete and accurate before proceeding with the hypothesis test.

Choosing the Appropriate Test in Excel

When conducting a hypothesis test in Excel, it's crucial to choose the right test for your specific scenario. Understanding the different types of hypothesis tests and how to select the appropriate one is essential for accurate and meaningful results.

Parametric Tests:

Nonparametric tests:, one-sample, two-sample, and paired tests:, goodness-of-fit tests:, chi-square tests:.

Choosing the right hypothesis test in Excel requires careful consideration of the nature of the data and the specific research question. Here are some key factors to consider when selecting the appropriate test:

  • Understanding the Data: Determine whether the data is continuous or categorical, and whether it follows a specific distribution.
  • Research Question: Clearly define the research question and the type of comparison or relationship being investigated.
  • Sample Size: Consider the size of the sample and whether it meets the assumptions of the chosen test.
  • Dependent or Independent Variables: Determine whether the variables are independent or related in some way, as this will impact the choice of test.
  • Assumptions: Ensure that the chosen test aligns with any specific assumptions or conditions required for accurate results.

Conducting the hypothesis test

When it comes to conducting a hypothesis test in Excel, there are a few key steps to follow in order to ensure accurate results. These steps include using the Data Analysis Toolpak and inputting the necessary parameters for the test.

The Data Analysis Toolpak is a powerful add-in for Excel that provides a variety of data analysis tools, including the ability to conduct hypothesis tests. To access the Toolpak, simply go to the "Data" tab, click on "Data Analysis" in the Analysis group, and select "t-Test: Two-Sample Assuming Equal Variances" for a two-sample t-test, or "t-Test: Paired Two Sample for Means" for a paired t-test.

Once the Data Analysis Toolpak is open, you will need to input the necessary parameters for the hypothesis test. This includes selecting the appropriate variables for analysis, specifying the significance level, and choosing whether to perform a one-tailed or two-tailed test. It is important to carefully review and input the correct parameters to ensure the accuracy of the test results.

By using the Data Analysis Toolpak in Excel and inputting the necessary parameters for the hypothesis test, you can effectively conduct hypothesis tests and analyze your data with confidence.

Interpreting the results

After performing a hypothesis test in Excel, it is important to understand how to interpret the results and make conclusions based on the data.

Identify the test statistic:

Look at the p-value:, consider the confidence interval:, check for statistical significance:, reject or fail to reject the null hypothesis:, consider the practical significance:, communicate the findings:, common mistakes to avoid.

When conducting a hypothesis test in Excel, there are some common mistakes that researchers often make. By being aware of these pitfalls, you can ensure that your results are accurate and reliable.

One of the most common mistakes when doing a hypothesis test in Excel is misinterpreting the results. It's important to carefully analyze the output of the test and understand what it is telling you. Avoid jumping to conclusions without thoroughly examining the data and the significance level.

Another mistake to avoid is using the wrong test for the hypothesis you are trying to test. Excel offers a variety of hypothesis tests, such as t-tests, F-tests, and chi-squared tests, among others. It's crucial to select the appropriate test for your specific research question and data set. Using the wrong test can lead to inaccurate results and conclusions.

In conclusion, hypothesis testing in Excel is a crucial tool for making data-driven decisions in various fields, from business to science. By using Excel, we can effectively analyze data and draw meaningful conclusions about our hypotheses.

As with any skill, practice makes perfect . So, I encourage you to continue exploring and practicing hypothesis testing in Excel. There are numerous resources available online that provide additional guidance and examples to help you master this valuable technique.

8. Click OK.

t-Test Result in Excel

Conclusion: We do a two-tail test (inequality). lf t Stat < -t Critical two-tail or t Stat > t Critical two-tail, we reject the null hypothesis. This is not the case, -2.365 < 1.473 < 2.365. Therefore, we do not reject the null hypothesis. The observed difference between the sample means (33 - 24.8) is not convincing enough to say that the average number of study hours between female and male students differ significantly.

Hypothesis tests are one of the major topics in the area of inferential statistics. There are multiple steps to conduct a hypothesis test and many of these require statistical calculations. Statistical software, such as Excel, can be used to perform hypothesis tests. We will see how the Excel function Z.TEST tests hypotheses about an unknown population mean.

Conditions and Assumptions

We begin by stating the assumptions and conditions for this type of hypothesis test. For inference about the mean we must have the following simple conditions:

  • The sample is a simple random sample .
  • The sample is small in size relative to the population . Typically this means that the population size is more than 20 times the size of the sample.
  • The variable being studied is normally distributed.
  • The population standard deviation is known.
  • The population mean is unknown.

All of these conditions are unlikely to be met in practice. However, these simple conditions and the corresponding hypothesis test are sometimes encountered early in a statistics class. After learning the process of a hypothesis test, these conditions are relaxed in order to work in a more realistic setting.

Structure of the Hypothesis Test

The particular hypothesis test we consider has the following form:

  • State the null and alternative hypotheses .
  • Calculate the test statistic, which is a z -score.
  • Calculate the p-value by using the normal distribution. In this case the p-value is the probability of obtaining at least as extreme as the observed test statistic, assuming the null hypothesis is true.
  • Compare the p-value with the level of significance to determine whether to reject or fail to reject the null hypothesis.

We see that steps two and three are computationally intensive compared two steps one and four. The Z.TEST function will perform these calculations for us.

Z.TEST Function

The Z.TEST function does all of the calculations from steps two and three above. It does a majority of the number crunching for our test and returns a p-value. There are three arguments to enter into the function, each of which is separated by a comma. The following explains the three types of arguments for this function.

  • The first argument for this function is an array of sample data. We must enter a range of cells that corresponds to the location of the sample data in our spreadsheet.
  • The second argument is the value of μ that we are testing in our hypotheses. So if our null hypothesis is H 0 : μ = 5, then we would enter a 5 for the second argument.
  • The third argument is the value of the known population standard deviation. Excel treats this as an optional argument

Notes and Warnings

There are a few things that should be noted about this function:

  • The p-value that is output from the function is one-sided. If we are conducting a two-sided test, then this value must be doubled.
  • The one-sided p-value output from the function assumes that the sample mean is greater than the value of μ we are testing against. If the sample mean is less than the value of the second argument, then we must subtract the output of the function from 1 to get the true p-value of our test.
  • The final argument for the population standard deviation is optional. If this is not entered, then this value is automatically replaced in Excel’s calculations by the sample standard deviation. When this is done, theoretically a t-test should be used instead.

We suppose that the following data are from a simple random sample of a normally distributed population of unknown mean and standard deviation of 3:

1, 2, 3, 3, 4, 4, 8, 10, 12

With a 10% level of significance we wish to test the hypothesis that the sample data are from a population with mean greater than 5. More formally, we have the following hypotheses:

  • H 0 : μ= 5
  • H a : μ > 5

We use Z.TEST in Excel to find the p-value for this hypothesis test.

  • Enter the data into a column in Excel. Suppose this is from cell A1 to A9
  • Into another cell enter =Z.TEST(A1:A9,5,3)
  • The result is 0.41207.
  • Since our p-value exceeds 10%, we fail to reject the null hypothesis.

The Z.TEST function can be used for lower tailed tests and two tailed tests as well. However the result is not as automatic as it was in this case. Please see here for other examples of using this function.

  • Array2: the second set of data to test
  • Tails: the number of tails where 1. is one-tailed distribution and 2 is for two tailed distribution
  • Type: 1 is for paired, 2 for homoscedastic, 3 for heteroscedastic

This is the data set and two arrays for my t hypothesis. I’d like to test the hypothesis if the is a difference in given arrays.

hypothesis testing data table

The formula I used for ttest hypothesis is  =T.TEST($B$2:$B$6,$C$2:$C$8,1,3) because the variance  of these arrays is different.

hypothesis testing ttest formula

Interpret the results of your hypothesis test in the context of your research question. Explain what the results mean and how they support or refute your hypothesis. To do that you need to interpret the calculated probability . Calculated p ≥ 0.05 means that difference is not significant and p ≤ 0.05 means that difference is significant. The hypotesis result is 0.406325 so the difference is not significant.

Hypothesized difference has been calculated but let’s check one more method with an add-in.

What is a Hypothesis Test?

A hypothesis test helps identify ways to reduce costs and improve quality. Hypothesis testing asks the question: Are two or more sets of data the same or different, statistically.

For companies working to improve operations, hypothesis tests help identify differences between machines, formulas, raw materials, etc. and whether the differences are statistically significant or not. Without such testing, teams can run around changing machine settings, formulas and so on causing more variation. These knee-jerk responses can amplify variation and cause more problems than doing nothing at all.

Three Types of Hypothesis Tests

  • Classical Method - comparing a test statistic to a critical value
  • p Value Method - the probability of a test statistic being contrary to the null hypothesis
  • Confidence Interval Method - is the test statistic between or outside of the confidence interval

How to Conduct a Hypothesis Test

  • Define the  null (H0) and an alternate (Ha) hypothesis .
  • Conduct the test.
  • Calculate the test statistic and the critical value (t-Test, F-test, z-Test, ANOVA, etc.).
  • Calculate a p value and compare it to a significance level (a) or confidence level (1-a).
  • Interpret the results to determine if you "cannot reject null hypothesis (accept null hypothesis)" or "reject the null hypothesis."

Excel formulas can be magical things, saving you time and combining vast arrays of data to speed up your number crunching. However, sometimes, the smallest error within your formula can frustratingly limit the quality and validity of your results. Let's take a look at the ways you can overcome these errors.

1. Check You've Used "="

The first part of an Excel formula must contain the "equals" symbol. This tells Excel that you are creating a calculation within your spreadsheet. If you don't use "=", Excel thinks that you're simply inputting data into the cell you're typing in, so it won't perform any calculations.

2. Use the Correct Number Formatting

Excel allows you to define the type of data you are inputting into a cell. In the Home tab on the ribbon, head to the "Number" group and click the drop-down arrow.

For the formula to work, ensure the correct number formatting is selected.

  • "General" works well, as it copies the formatting of other cells if you're referencing those in your formula—for example, if you're referencing two cells containing a currency, you'll probably want your result to be the same currency, and the "General" number format does this automatically.
  • "Number" is another good option. However, bear in mind that this generally gives a result with two decimal places, so you might want to change the number of decimal places after you have completed your formula.

Most other number formats are good choices depending on what type of result you're looking for. However, you must avoid "Text," as this tells Excel that you're placing text into the cell, so it won't see your input as a formula. This number format will result in what you type being displayed in that cell.

3. Avoid Circular References

When you press Enter after typing your formula, Excel might tell you that you have included circular references within your formula.

Excel sheet with a 'Circular Reference' warning showing.

This means that, within your formula, you have referenced the cell you're typing in. In the case above, the formula typed into cell F1 references the cell itself, which means that Excel cannot properly calculate what you're telling it to do. The best way to fix circular references is to close the warning that appears (click "X" or "OK"), press Ctrl+Z to undo what you just input, and type the formula again in a different cell.

4. Turn on "Automatic Calculation"

Another reason why your formula might not be working properly is that Automatic Calculation is turned off. If this is the case, the formula result will not automatically update when you change the data referred to in your formula.

To correct this, first, select the cell where you're inputting your formula. In the "Formulas" tab on the ribbon, go to the "Calculation" group, click the drop-down arrow next to "Calculation Options," and make sure the "Automatic" option is checked.

Excel sheet demonstrating where to find the 'Automatic Calculation' option.

If you want to ensure Automatic Calculations are turned on for your whole workbook, click "File" (top left corner of your Excel window), and then "Options" (bottom left corner of the menu that opens). In the window that opens, go to the "Formulas" menu and ensure "Automatic" is checked under the "Workbook Calculation" option.

Excel's options for automatic calculations, accessed through 'File', 'Options', and 'Formulas'.

These steps will tell Excel that you want it to recalculate if you change the data referred to in your formula.

5. Avoid Formatting Within Your Formula

As we stated in point 2, by default, if you're creating a formula that references a cell with a pre-defined number format, like a currency or a percentage, your formula will automatically copy the number formatting.

Excel formula containing dollar symbols incorrectly added as formatting.

In the example above, the person typing the formula wants to add two monetary values together within their formula. This can cause problems as certain symbols have certain functions within formulas. Instead of typing the currency symbols within their formula, they should use the accounting number format in the cell that they are typing, as this will automatically format their result to include the dollar symbols.

6. Review Your Formula for Extra Characters

This might sound obvious, but simply reviewing your formula manually can often highlight any issues straightaway. Look out for extra characters that shouldn't be there, spaces within cell references, or numbers that you might have typed accidentally when constructing your formula.

After having done this, you can also tell Excel to check for any errors for you. Click the "Formulas" tab on the ribbon, and in the Formula Auditing"group, click "Error Checking."

This will highlight most problems with your formulas.

7. Close All Parentheses

If you have a formula with several arguments, you will have used several opening parentheses.

=IFERROR ( AVERAGE (( TAKE ( Ratings!FZ4:INDIRECT ( "Ratings!GA"&$AI$9

In this formula that we have started to type, there are five opening parentheses. As a result, we need to ensure that each argument created by an opening parenthesis is completed, so we would need five closing parentheses to ensure our formula is correctly constructed.

8. Check Your Referenced Cells

Does your formula's result appear incorrect? If so, check that you have referenced the correct cells.

If you double-click on the cell containing your formula, Excel will color code the references within the formula. By doing this, we can quickly see if any of the cell references are incorrect. To fix this, simply drag the colored cell reference to the correct cell, and the formula will automatically update.

9. Use Excel's Function Guide

A good way to overcome frustrating formula errors is to use Excel's function guide instead of typing the formula manually. In the "Formulas" tab on the ribbon, click "Insert Function". Alternatively, click the same symbol next to your formula bar.

In the dialog box that opens, you can either type the name of the function you're looking to use in the "Search For A Function" box, or select from the list below. Once you've found the correct function, click 'OK', and Excel will take you through the steps to ensure your formula is correctly input.

10. Only Use Double Quotes for Text

If you include double quotes within your formula, Excel will see this as text to include in the result.

Here, we have used the IF function .

Excel formula using the IF function and highlighting the use of double quotes to create text.

In this example, if cell S9 is equal to 2, the formula will return the word "Yes". If it's not equal to 2, the formula will return "No". This is because we have used double quotes around these two words to tell Excel to add text to the cell containing the formula . So, if your formula doesn't work, make sure you have not used double quotes accidentally.

11. Don't Nest More Than 64 Functions

If you use functions within arguments in Excel, you are nesting your formula.

In this example, we are nesting the AVERAGE and SUM functions within the IF function.

= IF ( AVERAGE (A1:A10)>100, SUM (B1:B113),"FAIL")

Excel allows a maximum of 64 nested functions within one formula. If you use more, the formula will not work.

12. Don't Try to Divide by 0

Have you ever tried to use a calculator to divide by zero? If so, you'll know that it returns an error. This is because it's impossible to divide by 0. If you try to do this in Excel, you'll see

In this example, Dick's profit per hour returns the above error, because he hasn't worked any hours.

Dividing by 0-1

To get around this, you would use the IFERROR function to hide the error and insert an alternative value or return a blank cell.

Now that you know how to troubleshoot errors in Excel formulas, you can also evaluate formulas , which can be useful if you want to break down a formula that someone else has typed.
