In this post, I provide step-by-step instructions for using Excel to perform t-tests. Importantly, I also show you how to select the correct form of t-test, choose the right options, and interpret the results. I also include links to additional resources I’ve written, which present clea...
Likewise, the range B4:B24 is the second array on which the t-test is to be performed. Further, we have entered the “tails” and “type” arguments as 1. This is because a one-tailed, paired t-test needs to be performed. Interpretation: To accept or reject the null hypothesis, ...
The results of a two factor without replication analysis are the following. Result Interpretation Parameters: Two-factor ANOVA Analysis Without Replication has similar parameters to the single factor ANOVA. Test Statistic (F) vs Critical Value (FCrit): For both variables, the Statistic values (F=...

A t-test is a statistical tool that checks if there is any difference or correlation between two different sets of data. The t-test formula checks this by comparing the averages of both data sets. Imagine you have two groups of plants, one group receives a new fertilizer, and another rec...
Generally, even if one variance is up to 3 or 4 times the other, the equal variance assumption will give good results, especially if the sample sizes are equal or almost equal. This rule of thumb is clearly violated in Example 2, and so we need to use the t-test with unequal populati...
This is very close to the desired result, isn't it? To get rid of theNotecolumn, which has become redundant, copy the contents of theIconcolumn, and then use thePaste Specialfeature topaste as valuesin the same place. However, please keep in mind that this will make your icons static...
Also, select where you would like the results to be displayed. In this example, I selected ‘Output Range’ and selected an empty cell next to the data. The output The output of the statistical test given is more informative than using the T-test formula directly, which only gives you th...
I’m not quite sure about the interpretation of the results of the F test. As you state, Excel functions FTest or F.Test give “the two-tailed probability that the variance of the data in ranges R1 and R2 are not significantly different”. On the other hand, in example 1, it is sa...
