The following are the statistical data of an experimental group and a control group in one of the experiments comparing the results of structured learning with traditional learning, and clarify whether there are statistically significant differences between the average scores of the two groups? With the calculation of the size of the effect?

Statistical data	persons number	average	standard deviation	median
experimental group	101	55.02	16.32	54.02
control group	91	53.20	14.66	52.39

- tabular = 61.2 at level of significance = 0.01

- T = 1.97 at level of significance = 0.05
