WebThe null hypothesis for the independent samples t-test is μ 1 = μ 2.So it assumes the means are equal. With the paired t test, the null hypothesis is that the pairwise difference between the two tests is equal (H 0: µ d = 0).. Paired Samples T Test By hand.

The test statistic for our independent samples t -test takes on the same logical structure and format as our other t -tests: our observed effect (one mean subtracted from the other mean), all divided by the standard error: t = ( X 1 ¯ − X 2 ¯) S E. Calculating our standard error, as we will see next, is where the biggest ...
