Paired Samples T Test Graph. The assumptions that should be met to perform a paired samples t test. The last one paired samples test shows the actual test results.
The assumptions that should be met to perform a paired samples t test. The last one paired samples test shows the actual test results. The confidence interval for the difference between means shown on the right graph was copy and pasted from the paired t test results.
A paired samples t test is used to compare the means of two samples when each observation in one sample can be paired with an observation in the other sample.
Suppose we want to know whether a certain study program significantly impacts student performance on a particular exam. A t test for two paired samples is a hypothesis test that attempts to make a claim about the population means mu 1 and mu 2.
