Computes statistics for the independent groups t-test, also know as the two sample t-test. It is designed to compare the means of observations in the same column between two groups. The node allows the testing of equality of variances (Levene's test) and the t-value for both equal- and unequal-variance. It also provides the relevant descriptive statistics.
