What does unimodal mean?
One hump
The essential piece of a research design to be a true experimental design.
Random assignment
What type of independent variables are used in multiple regression?

Why are RCTs considered the gold standard for research design?
They are the only type of study that can draw causal conclusions.
What type of independent variables are used in logistic regression?
Categorical
This kind of test is used when we’re only looking for an effect in one direction
one-tailed test
Name one way to compare prevalence

What type of significance do researchers strive for in their studies?
Practical Significance
You want to investigate the effects of a treatment for anxiety on men and women, but you worry about age being a variable that may alter results. What research design should you use?
ANCOVA
What type of factor analysis tests a preexisting model?
Confirmatory factor analysis
This statistical technique adjusts alpha when multiple tests are run to control Type I error risk
Bonferroni correction
The percentage of cases correctly identified as falling within the target group
Sensitivity
What are the two primary types of effect size?
Cohen’s d & Correlation Coefficient
You want to see whether a CBT treatment or an ACT treatment is most effective for long-term depression, while also comparing how clinician training affects the effectiveness of treatment. What research design should you use?
Factorial ANOVA or a factorial design
What kind of factor analysis is a Structural Equation Model (SEM)?
Confirmatory factor analysis
This test analyzes more than one dependent variable at once
MANOVA
The number of cases correctly identified as falling within the nontarget group
Specificity
What three scores make up the Classical Test Theory?
Obtained Score, True Score, Error Score

Case study
What type of variable is present within a partial correlation that is not an independent or dependent variable?
“Partial out variable” “variable that is held constant” “variable that is controlled for”
This test is used for nominal data, like diagnosis or gender categories
Chi-squared test
