1. calculating some test statistic. 2. comparing that statistic to an underlying distribution to determine how likely it would be to occur by chance. For example, in the coin-tossing example: the test statistic we used was the number of heads obtained. the underlying distribution was the binomial distribution where P = 0.50 and N = 18

Calculating the Test Statistics for Testing Two Means. Need: Data are Normal. We will focus on the case that and are unknown (and may not be the same) Test statistic is . Then this test statistic will have a t-distribution with the following df: df = (round down!!!) Note that the test statistic should be consistent with your hypotheses.

This Tip Sheet provides an overview of how to perform the single-sample t test in Excel, which includes calculating the test statistic, finding the appropriate critical value for comparison, and finding the p-value of the computed t statistic. The formula for the single-sample t statistic is shown below.

If the test statistic is higher than the critical value, the probability of getting that result by chance is very small (a 5% or less chance), and we can reject the null hypothesis. If the test statistic is less than the critical value, the probability of calculating that value will be …

What test statistic will I employ? What is the standard deviation (in the population) of the criterion variable? For correlated samples designs, what is the correlation (in the population) between groups? In my opinion, if one considers Type I and Type II errors equally serious, then one should have enough power to make ( = (.
