Paired T-test will analyze two sample datasets with a two sample T-test procedure. The samples can be paired or non-paired. A summary table is produced along with graphics showing the statistical significance at the 90%, 95%, 97.5%, 98%, 99% and 99.5% levels depending on if the test is 1-tailed or 2-tailed. A paired T-test is the same as a Randomized Block ANOVA with only two treatments. Note that this is a two sample t-test app. For a single sample refer to the “Student T-test” app.
