Independent T Test Example. This sample outcome thus suggest that the population means weren t equal after all. Before running the independent samples t test it is a good idea to look at descriptive.
An independent samples t test evaluates if 2 populations have equal means on some variable. Your variable of interest should be continuous be normally distributed and have a similar spread between your 2 groups. There is a paired data also called correlated data t test that compares two samples from data that is related like pretest score and post test score.
T test sample mean 1 sample mean 2 sqrt s1 2 n1 s2 2 n2.
What is an independent samples t test. Your variable of interest should be continuous be normally distributed and have a similar spread between your 2 groups. Independent samples t test when variances are not equal problem statement. The independent samples t test is a statistical test used to determine if 2 groups are significantly different from each other on your variable of interest.
