Question

Quizplus · Accepted Answer

The best choice for a comparison group would be a group of male high school math teachers with low scores on authoritarianism. This group would be similar to the experimental group in terms of gender and subject matter expertise (math teaching), but would differ in terms of their level of authoritarianism. This would provide the most control for the study and help isolate the influence of authoritarianism on students' attitudes toward math. Choosing a group of high school teachers with low scores on authoritarianism (Option A) would not be specifically focused on math teachers and could introduce additional variability, while choosing a group of high school math teachers with low scores on authoritarianism (Option B) would not provide an adequate comparison for the high authoritarianism group.
