The data show the test results from students in two classrooms, one integrated and one not. There are two sets of test scores, a pre-test and a post-test for both groups. First, calculate a measure of change in the test scores for students in both groups. Then, use the resulting measure of change to compare both groups on the measure of change from the pre-test to the post-test. When finished, write a short summary of what you found, including: Group 1 mean Group 2 mean Ho and H1 t-observed t-critical

State the empirical rule for variables.

The mode is the only measure of central tendency that is appropriate to utilize for a variable measured with which scale of measurement? ordinal nominal interval ratio
