Depending on the test you run, you may see other statistics that were used to calculate the P value, including the mean difference, t statistic, degrees of freedom, and standard error. The confidence interval and a review of your dataset is given as well on the results page. ...
We want to use these results to test $H_0: \mu_1=\mu_2$ versus $H_a: \mu_1\ne\mu_2$. Find the test statistic for this test. The t-test calculator, work with steps, formula and practice problems would be very useful for grade school students (K-12 education) to learn what ...
This Test Statistic Calculator calculates the test statistic of either one population mean, comparing two population means, or one population proportion.
t-Test Calculator is a tool used to determine whether there is a statistically significant difference between the means of two independent groups. What is a t-Statistic? The t-Statistic is a value derived from your sample data that measures the size of the difference relative to the variation...
