Statistical Tests: I.V.s & Groups ONLY Flashcards
T-Test
Independent Variable(s) : 1 I.V. G: 2 Groups
One-Way ANOVA
Independent Variable(s): 1 I.V. G: 2+ Groups
Factorial ANOVA
Independent Variables(s): 2+ I.V. (I.V.s called Factors)
Two-Way ANOVA
I.V.: 2+ I.V.s
Multivariate Analysis of Variance (MANOVA)
Independent Variable(s): 2+ I.V.s
If groups are said to “not be related,” what type of design is this?
Between-Groups Design
If groups are said to “be related,” what type of design is this?
Within-Subjects Design
What tests do you run for a between-groups (not related) design?
- Independent t-test
2. Between measure of ANOVA
What tests do you run for a within-groups (related) design?
- Dependent (paired) t-test
2. Repeated measures of ANOVA
What does an independent samples t-test test for?
Tests to compare the means of two different groups
(n >30)
What does a paired t-test test for?
Repeats measurement on the same individual/groups
Key Point: there is a before and after (pre and post test)
See table in notes. How would you write a statement interpreting this?
For t(108) = 5.43, there was a significant effect for group A, with group A receiving higher scores than group B.
What type of test:
Do men and women differ in empathy skill?
Independent samples t-test
What type of test:
Does the average score on memory tests after the cognitive training significantly differ from their average score before training?
Paired t-test
