What is T-test?
T-test definition and meaning on Health terms:
A t-test is a statistical test that helps compare whether the average values of two groups of data are significantly different from each other. It is used to obtain a measure of the difference between the means (averages) of the groups, relative to the spread of data within each group. The t-test helps decide whether a difference in mean values between two groups is due to random chance in a sample selection.
