" you should calculate your Z-score. This important statistics tool not only takes into account the average of all the test scores but also the variation in the results. To find the Z-score, you subtract
Step 1: Calculate the Sample Mean To calculate a mean (often referred to as an average), add the individual values of your sample together and divide by n, the total items in your sample. For example, if your sample includes five quiz scores and the individual values are 63, 89...
Calculate the degrees of freedom by totaling the number of observations for both groups and dividing by 2. Determine your alpha level and look up the intersection of degrees of freedom and alpha in a statistics table. If the value is less than or equal to your calculated t-score, the resul...
