Independent T Test Example. Your variable of interest should be continuous be normally distributed and have a similar spread between your 2 groups. What is an independent samples t test.
There is an independent samples t test this example that compares two samples to each other. This sample outcome thus suggest that the population means weren t equal after all. T test sample mean 1 sample mean 2 sqrt s1 2 n1 s2 2 n2.
T test sample mean 1 sample mean 2 sqrt s1 2 n1 s2 2 n2.
T test sample mean 1 sample mean 2 sqrt s1 2 n1 s2 2 n2. 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. If the population means are really equal then the sample means will probably differ a little bit but not too much. Before running the independent samples t test it is a good idea to look at descriptive.
