I am psueo conducting an experiment on 144 freshmen high school students who are evenly divided into 6 groups. The treatment group are receiving a new instructional strategy that the control group is not receiving. A t-test was conducted after a pre-test of a CBM measurement, and the results indicated no significant differences between all the groups. What is the Experimental groups mean and standard deviation scores and what are the control groups mean and standard deviation scores?
