SEM is the SD of the theoretical distribution of the sample means (the sampling distribution). An independent-group t test can be carried out for a comparison of means between two independent groups, with a paired t test for paired data.

Standard Error Calculator Theoretically, the SD from the control group is the best estimate of SD of the population as the members of the control group are sampled from the population without any treatment. As the t test is a parametric test, samples should meet certain preconditions, such as normality, equal variances and independence.
