WebThe Paired-Samples T Test procedure compares the means of two variables for a single group. The procedure computes the differences between values of the two variables for each case and tests whether the average differs from 0. Example. WebThe idea behind the paired t-test is to reduce the data from two samples to just one sample of the differences, and use these observed differences as data for inference about a single mean — the mean of the differences, μ d. The paired t-test is therefore simply a one-sample t-test for the mean of the differences μ d, where the null value is 0. WebHow can a t-test?. A t-test (also familiar as Student's liothyronine-test) is one tool for evaluating to means of one or double populations using assumption testing.A t-test may be used to evaluate whether a single group differs from adenine known rate (a one-sample t-test), if two groups differ from anyone other (an independent two-sample t-test), or … ct state treasury office
