How to Calculate P Value in Google Sheets (2024 Update)

May 8, 2024

P Value in Google Sheets

In Google Sheets, a "p-value" measures the significance of statistical test results which helps decide whether to reject the null hypothesis usually at a significance level of 0.05. Google Sheets doesn't have a direct "p-value" function, but you can calculate it using T.TEST or CHITEST for different analyses to determine your data's statistical relevance.

How to Calculate P Value in Google Sheets

Follow the steps below to calculate p value in Google Sheets. 

1. Input Dataset for Two Groups into Google Sheets

Begin by entering the test scores into Google Sheets. In Column A, label it "Group A" and in Column B, label it "Group B". This setup allows for a direct comparison between the two teaching methods.

2. Install the 'XLMiner Analysis ToolPak' Add-on for Statistical Analysis

To analyze the data, you need additional functions not available in Google Sheets by default. Install "XLMiner Analysis ToolPak" by navigating to Extensions > Add-ons > Get add-ons.

3. Select 'Two-Sample Assuming Equal Variances' T-Test 

Open XLMiner Analysis ToolPak by clicking "Use".

Choose the 'F-Test Two-Sample for Variances'. This selection is suitable for comparing the means of Group A and Group B, assuming the variances between the two groups are similar.

4. Specify Data Ranges for Group A and Group B 

In the tool's dialog, enter A2:A11 for Group A and B2:B11 for Group B. For results, either pick an empty area like G12 or opt for a new sheet to ensure organized and clear output. After setting up your data, click "OK" to execute the t-test.

6. Interpret the Combined Results from T-Test and F-Test for Variances

The P value obtained from the F-test for variances is approximately 0.3. This indicates there is not a statistically significant difference in variances between the two groups of scores. The result supports the assumption of equal variances, which is necessary for the two-sample t-test assuming equal variances that was chosen for this analysis. 

This outcome suggests that the differences in teaching methods do not lead to significantly different variances in test scores which allows for a fair comparison of their means under the assumption of equal variances.
