Question

Dr. Sanderson is curious as to whether exposing people to violent video games causes them to be more aggressive. She assigns half her participants to play a violent video game for 5 minutes and the other half to play the same game for 25 minutes. Afterward, she has them play a board game and has a well-trained coder determine whether they are very aggressive in their playing style, barely aggressive, or not at all aggressive. She finds that a vast majority of her participants, regardless of group assignment, are rated as very aggressive. This outcome would be known as a(n) _____. floor effect ceiling effect weak manipulation outlier

Answer 1

CEILING EFFECT. Ceiling effect occurs when an independent variable no longer had any effect on the dependent variable or when the score won't get any higher for a specimen because they have already reached the highest score possible on the test. Ceiling effect is the correct answer because Dr. Sanderson's items in the test are not challenging enough for the group of individuals.
