Has implemented two different writing intervention programmes in two schools for the deaf- a different one in each school. The purpose of the interventions is to raise the level of the students’ abilities to express themselves in writing. She did both a pre-test and a different post-test of the students’ abilities. All students received the same pre-test and then again the same post test (different from pre-test). T he written assignments were scored using a valid literature scale. Below are % improvements (based on difference in scores between the pre-test and post test for 15 children from each school( S1 and S2). Determine at the 5 % critical level if the two programmes were equally successful.
S1 60 75 50 55 59 72 30 44 48 56 62 67 53 57 60
S2 65 70 52 58 59 64 36 45 49 57 63 80 56 55 63
