Which of the following would cause F _obt to increase? A) an increase in the difference between the means B) an increase in the within-groups variability C) an increase in the magnitude of the independent variable's effect D) an increase in the difference between the means and an increase in the within-groups variability E) an increase in the difference between the means and an increase in the magnitude of the independent variable's effect

Question

Quizplus · Accepted Answer

F _obt represents the effect size, which is the difference between the means divided by the standard deviation of the data. Therefore, an increase in the difference between the means will increase the effect size, as will an increase in the magnitude of the independent variable's effect. An increase in the within-groups variability will decrease the effect size, so option B can be eliminated. However, option D is a combination of options A and B, which would have opposite effects on the effect size. Therefore, the best choice is E, as it includes the two factors that would increase the effect size.
