Question 9

In a certain study, black and white teachers from a large inner city school were asked to rate the same black and white students for "adaptive behavior" on a behavior rating scale. The two factors in the experiment, then, were teacher ethnicity and pupil ethnicity. On average, white teachers rated black pupils 32, and white pupils 50. On average, black teachers rated black pupils 47, and white pupils 30. Both null hypotheses for the main effects were tenable, but there was significant interaction between the teacher ethnicity and pupil ethnicity factors. Graph the means and discuss the nature of the interaction and your conclusions. What type of interaction is present?

Accepted Answer

To graph the means, we can create a bar

Question 17

Dr. Caster decides to perform an experiment investigating the effects of caffeine and sugar on motor skill performance. He randomly assigns his subjects to one of four groups: high caffeine/high sugar, high caffeine/no sugar, no caffeine/high sugar, no caffeine/no sugar. People in each group are given a soft drink containing the appropriate levels of sugar and caffeine, and then tested on a mirror tracing task. Dr. Caster finds that the people in two of the groups the high caffeine/high sugar and the no caffeine/no sugar) perform at about the same high level, while the other two groups the no caffeine/high sugar and high caffeine/no sugar) perform at about the same poor level. Dr. Caster's results show
