t-tests are used to determine whether two samples are different. For example, two sixth grade classes (random samples) took the same reading pre and post-tests. The T-Test will help us analyze whether the two means are different. This means we are comparing the mean of fifth-grade class #1 to fifth grade class #2 to see how they vary. This will help to figure out if students are increasing performance overall or not. Also, if there is significant difference, the t-test will help us figure out if we need to investigate further to see why there is significant differences in performance (intervention, supplemental materials, delivery method of instruction, etc).
