Appendix 2. Results of t-tests (and their associated efect sizes) comparing growth, MOY averages and EOY averages in scores between the treatment and control groups can be found in Appendix 4.
Tables 14-15 report the efect sizes (Cohen’s d) resulting from dependent samples t-test that compared growth and EOY average in literacy scores in the treatment and comparison groups. T-tests were run separately for grades 1-3 and then together for Grades 3-5 due to small sample sizes in grades 4 and5.
