Stan is conducting a class research project in which he compares manual dexterity in two groups of randomly assigned participant
s: one group is sober and the other has consumed 2 ounces of 75 proof alcohol. What statistical test should Stan use to see whether the two groups differ in manual dexterity?
t-test is an inferential statistic analysis which is used to determine whether there is a difference between mean score of two groups. Here, we have two groups with one independent variable (manual dexterity), so t-test is appropriate.
