Many health professionals recommend that women practice, Ask an Expert

Statistics

Many health professionals recommend that women practice monthly breast self-examination (BSE) to detect breast cancer in its early stages (when treatment is much more effective). Several methods are used to teach BSE. T. S. Spatz (1991) compared the method recommended by the American Cancer Society (ACS) to the 4MAT method, a method based on different learning styles that different people have.

She also included an untrained control group. The dependent variable was the amount of information retained three months after training. Analyze the data in the table with an ANOVA, HSD tests, and f. Write a conclusion.

	ACS	4MAT	Control
X	178	362	62
X2	2619	7652	1192
N	20	20	20
