How to Do a Chi Square Test in Google Sheets

The CHISQ.TEST function can be used to perform the Chi-square test easily in Google Sheets:

The syntax for the function is CHISQ.TEST(actual_range, expected_range), where:

• actual_range is the range of observed frequencies (your data without totals).
• expected_range is the range of expected frequencies.

Here's how you can apply it:

Step 1: Organize Your Data

First, you need to organize your data into a contingency table format. Suppose you're looking at the relationship between Gender (Male/Female) and Preference for a new product (Like/Dislike). Your table might look something like this:

Step 2: Calculate Expected Frequencies

Before using the CHISQ.TEST function, you need to calculate the expected frequencies for each category based on your total observations. The formula for expected frequency is: (Row Total * Column Total) / Grand Total.

For example, for the "Male (Like)" category:

Row Total for Male = 50

Column Total for Like = 45

Grand Total = 100

The expected frequency for Male who like the product would be (50 * 45) / 100 = 22.5.

You'll need to calculate this for each cell in your contingency table.

Step 3: Perform the Chi-Square Test

Assuming observed frequencies are in B2:C3 and expected frequencies are in E2:F3, your Chi-square formula will be:

=CHISQ.TEST(B2:C3, E2:F3)

Press Enter to execute the formula. This will give you the chi-square test statistic.

Step 4: Interpret the Results

The result of the chi-square test will give you a p-value.

• If the p-value is less than your chosen significance level (usually 0.05), you can reject the null hypothesis, concluding that there is a significant association between the variables.
• If the p-value is greater than your chosen significance level, you fail to reject the null hypothesis, indicating that there is not enough evidence to suggest a significant association between the variables.
