Test the mean difference between two samples of continuous data using the 2-sample t-test. The calculator uses the probabilities from the student t distribution. For all t-tests see the easyT Excel Calculator : : Sample data is available. Fore more information on 2-Sample t-tests View the Comparing Two Means: 2 Sample t-test tutorial

Today we calculated the p-value from a given z-test statistic, for a two-sided test, a left-tailed test, and a right-tailed test. For each test, we performed the calculation using three different methods: z-table, graphing calculator, and Excel. Good luck!

Accordingly, the test statistics can be transformed in effect sizes (comp. Fritz, Morris & Richler, 2012, p. 12; Cohen, 2008). Here you can find an effect size calculator for the test statistics of the Wilcoxon signed-rank test, Mann-Whitney-U or Kruskal-Wallis-H in order to calculate η 2. Enter the sample mean, population mean, standard deviation, and sample size into the t statistic calculator to determine the t-value of that set of data. Test the mean difference between two samples of continuous data using the 2-sample t-test.
