⩥ What does an eigenvalue indicate in principal components analysis?
Answer: The amount of variability across all items accounted for by an
independent factor/component.
⩥ What is an example of a research question tested using a one-way
repeated measures ANOVA?
Answer: Do levels of depression change from month to month for
individuals in bereavement support groups?
⩥ What is the primary purpose of Factorial ANOVA?
Answer: To understand if there are interactions between independent
variables on the dependent variable.
⩥ What should be true when employing multiple regression analysis to
predict outcomes?
Answer: There should be low intercorrelations among predictors and
high correlation of each predictor with the criterion.
,⩥ What are the requirements for using ANCOVA?
Answer: 1 nominal between subjects independent variable and 1
continuous dependent variable.
⩥ How many dummy variables are created from a categorical variable
with 6 levels in logistic regression?
Answer: 5 dummy variables.
⩥ What feature in Qualtrics allows moving a participant to a later
question based on previous responses?
Answer: Skip logic.
⩥ In the hypothesis that meditation reduces rumination, what is
rumination considered?
Answer: A mediator variable.
⩥ What analysis may be helpful in meta-analysis if there is too much
heterogeneity?
Answer: Subgroup analysis.
⩥ What best describes content validity in measurement development?
Answer: The extent to which items adequately represent the construct
domain.
,⩥ What is required to calculate Cohen's d for effect size?
Answer: Means of the experimental and control groups.
⩥ What types of plots are useful tools in a meta-analysis?
Answer: Forest plot and funnel plot.
⩥ What is NOT true about fail rates in measurement instruments?
Answer: Fail rate should be different across different forms of a test.
⩥ How does Confirmatory Factor Analysis differ from Principal
Components Analysis?
Answer: You already have a number of dimensions you believe are
underlying the items.
⩥ Are omnibus ANOVA hypotheses always 1-tailed?
Answer: False.
⩥ What is the typical power percentage aimed for in studies?
Answer: 80% power.
⩥ What does the region of rejection represent?
, Answer: Alpha.
⩥ What is a moderator in research?
Answer: An interaction variable.
⩥ What is the structure of logistic regression?
Answer: 1 dichotomous dependent variable and 2 or more predictors.
⩥ What factors affect power in research?
Answer: Sample size, effect size, alpha level.
⩥ What defines a good covariate?
Answer: It is correlated with the dependent variable.
⩥ What is the difference between multiple regression and logistic
regression?
Answer: Multiple regression does not analyze the raw outcome variable
like logistic regression does.
⩥ What is the function of a one-way repeated measures ANOVA?
Answer: To look for mean differences among 3 or more groups at
different time points.
