Independent Samples T Test Chart. An independent samples t test evaluates if 2 populations have equal means on some variable. The last 4 variables in our data file hold our test scores.
Note that this discussion assumes an independent samples t test. The independent samples t test compares the means of two independent groups in order to. This sample outcome thus suggest that the population.
If the population means are really equal then the sample means will probably differ a little bit but not too much.
Your variable of interest should be continuous be normally distributed and have a similar spread between your 2 groups. Note that this discussion assumes an independent samples t test. In cell next to the label enter the following equation to calculate the se for the t test. For each variable we ll use a t test to evaluate if the mean scores are different between our 2 groups of children.
