The independent t test also called the two sample t test independent samples t test or student s t test is an inferential statistical test that determines whether there is a statistically significant difference between the means in two unrelated groups.
If the population means are really equal then the sample means will probably differ a little bit but not too much. The assumptions that should be met to perform a two sample t test. The independent samples t test is a parametric test.
Independent measures t test.
Very different sample means are highly unlikely if the population means are equal. The independent samples t test is a parametric test. Null and alternative hypotheses for the independent t test. Your variable of interest should be continuous be normally distributed and have a similar spread between your 2 groups.
