STAT101: A Review of the Basics
... There are three ways to compare the means of two groups -- the independent t-test, paired samples t-test (dependent t-test), and the Wilcoxon test. The independent t-test is used for unrelated groups. For example, to compare treatment and control groups or males and females. The dependent t-test com ...

Basic Concepts
... trainee example, the two chemists are analyzing the same unknown, but obtain different means. The t-test of means can be used to determine whether the difference of the means is significant. The t-value is the same as that used in for determining confidence intervals. This makes sense; the goal of t ...
