Multiple Choice

A researcher conducts a two-factor study to evaluate the effect of a medication for males and for females.

• A) The medication lowers scores by around 10 points and the effect is the same for males and females.
• B) Although the average effect of the medication is to lower scores by 10 points, the exact effect depends on the gender of the participant.
• C) Because there is an interaction, you cannot conclude that the medication has any effect.
• D) Additional information is needed to come to a conclusion.
