Independent t-test analysis

An independent t-test is a parametric test to assess the difference of two group means. This test assumes variances of the groups are equal, which can be assessed using Levene's test. After running the t-test analysis, an effect size and power analysis must be computed to determine the confidence that can be had in the t-test results.
