A researcher examined the effect of distraction (i.e., no distraction vs. high level of distraction) and reward size (no reward vs. $10 reward) on task performance. He used a two-factor ANOVA to analyze his data. If the results of ANOVA showed a significant effect of distraction on task performance that means A. the mean performance of participants tested under different levels of distraction is significantly different. B. the mean performance of participants tested under different levels of reward is significantly different. C. the reward affects performance differently depending on the level of distraction. D. None of the above.

A psychologist would like to examine the effects of distractions on the concentration level of elementary school children. Three samples of children are selected with n = 4 in each sample. One group experiences no distraction, one group experiences a visual distraction, and the third group experiences a visual and auditory distraction. The psychologist records the number of mistakes on a concentration task for each child, with higher values indicating more mistakes. Do the data below indicate any significant differences among the three groups?

A researcher conducts two studies using the one-way between-subjects ANOVA. The sum of squares between groups is smaller in Study 1 than in Study 2; the sum of squares total is the same in both studies. Using eta-squared, in which study will the effect size be larger? a. Study 1. b. Study 2. c. There is not enough information to answer this question.
A study collects data on average combined SAT scores (Math + Evidence-Based Reading and Writing) and percentage of students who took the exam at 100 randomly selected high schools. The following is part of the computer printout for regression: Which of the following is a correct conclusion? (A) "SAT" in the variable column indicates that SAT score is the dependent (response) variable. (B) The correlation is 0.875 . (C) The $y$ -intercept indicates the mean combined SAT score if percent of students taking the exam has no effect on combined SAT scores. (D) The $r^{2}$ value indicates that the residual plot does not show a strong pattern. (E) Schools with lower percentages of students taking the exam tend to have higher average combined SAT scores.
