A t test compares the means of two groups. There are several types of two sample t tests and this calculator focuses on the three most common: unpaired, welch's, and paired t tests. Directions for using the calculator are listed below, along with more information about two sample t tests...
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 ...
The test statistic is χ2=0.066+1.066+1.066+0.066=2.264. For a Chi-Square distribution with 4-1=3 degrees of freedom, we compute the p-value using an online calculator (such as https://www.statology.org/chi-square-p-value-calculator/), to get that the ...

After making the t-test adjustments, this is 45.5%, lower than the value we obtained above using the Z-distribution. On the left panel the calculator shows that the minimum sample size required in order to achieve power of 80% is 8. So you would need at least 8 units to be assured ...
