EXAM 4 STUDY GUIDE & PRACTICE TEST 2026/2027
Single factor design - correct answer ✔✔One IV
Can use withing subject or between subject manipulations
Factorial designs - correct answer ✔✔Multiple IVs
Can use withing subject, between subject, or mixed factor manipulations
Main effect - correct answer ✔✔How each IV affects the DV
-measured by factorial designs
Interaction effect - correct answer ✔✔How IVs work together to affect the DV
-the effects of one IV differ depending on the level of another IV
-measured by factorial desgins
-EX: t-tests
When do you use a repeated measures analysis of variance? - correct answer ✔✔Used for both within
subject and mixed factor designs
ANOVA - correct answer ✔✔Used when only one DV is being measured
- generates F score and p value
Post Hoc Tests - correct answer ✔✔- only run if F is significant
- Planned (a priori)
