How to perform t-test in Excel
The Student's t-test or simply t-test tells you how significant the differences between groups are. It can either be paired or unpaired t-test depending on whether the data is paired or unpaired. The ultimate goal for you is to find the p value and if it is less than 0.05 then there is significant difference between the two groups. If it is more than 0.05 then there is no significant difference between the two groups.
