1. What is the correct way to report a Chi Square result? There were 100 participants and there were three grouping variables.
Group of answer choices
-X2(2, 100) = 12.55, p < .01
-X2(2, n = 100) = 12.55, p < .01
-X2(3, 100) = 12.55, p < .01
-X2(3, n = 100) = 12.55, p < .01
2. A researcher wanted to know if anxiety predicts attentional bias. To do this they calculated anxiety scores for each participant and assessed attentional bias. What test should the researcher do?
Group of answer choices

-Independent Sample t-test
-Regression
-Correlation
3. A researcher wanted to see which facial expression captured attention faster. To test this they had a sample of 30 participants that completed at task consisting of fearful, happy, angry, and neutral faces. What statistical test did the researchers use to determine differences in attention between the faces?
Group of answer choices
-Paired sample t-test
-Regression
-One way between groups ANOVA
-One way repeated measures ANOVA
-Chi Square
4. If a researcher conducted a t-test and it was not significant but the effect size was very large, what might have driven the insignificant t-test?
Group of answer choices
-Small sample size
-Small standard deviation
-Large standard deviation
-Large sample size
5. A researcher wants to examine if high anxiety is associated with increased attentional bias. If the researcher plans on doing an independent sample t-test, how should the researcher design the study?
Group of answer choices
-Use the anxiety to predict attentional bias
-Measure attentional bias and then put the participants through a stressful task to increase anxiety and then measure attentional bias again
-Select participants that either have high or low anxiety and compare the two
-Divide the participants into three groups and compare the means
