Pretest data and statistical feature analysis of experimental class and control class (pretest).

		Number of people	Average score	Standard deviation	Corresponding quadrant	Statistical characteristics
Pretest	Experimental class	42	36.07	11.177	Beta quadrant	The average level is low but scattered, and there are high-score students
	Control class	38	36.32	11.526	Beta quadrant	The average level is low but scattered, and there are high-score students

Pretest Z = −0.070, |Z| < 1.96, so there was no significant difference between the two groups.
