This chapter describes the difference between paired and unpaired data and it demonstrates that the paired t-test has greater power than the two-sample t-test when dealing with paired data. The paired t-test is used where data form natural pairs. Its classic use arises when we've observed ...

The paired t test analyzes the differences between pairs. For each pair, you calculate the difference. Then you calculate the average difference, the 95% CI of that difference, and a P value testing the null hypothesis that the set of differences is sampled from a population where the mean ...

heatmap showing the enrichment of various cell types in the proximal and distal regions for each CAF subpopulation. The paired t-test was used to compare the differences in cell proportions between the proximal and distal regions for each CAF subpopulation. Red color represents enrichment of a cel...

Dependent t-test for paired samplesWhat does this test do?The dependent t-test (also called the paired t-test or paired-samples t-test) compares the means of two related groups to determine whether there is a statistically significant difference between these means.What variables do you need ...
Statistical differences between groups were analyzed using the paired t-test and one-way analysis of variance. The results of the in vitro studies were also analyzed using one-way analysis of variance. A P-value of <0.05 was considered statistically significant. Results The FimA Ab inhibits ...
