T-Test Analysis Sample Size at John Mcfadden blog

T-Test Analysis Sample Size. A t test is a statistical hypothesis test that assesses sample means to draw conclusions about population means. There is no minimum sample size for the t test to be valid other than it be large enough to calculate the test statistic. The overall effect is that as the. The test for equality of variances is dependent on the sample size. A rule of thumb is that if the ratio of the larger to smaller standard deviation is greater than two, then the unequal variance test. Use power analysis for sample size estimation for all studies. Validity requires that the assumptions for the test statistic hold approximately. Frequently, analysts use a t test to determine whether the population means.
