Tests of Differences: Parametric
Cards in this deck (13)
- 1What are the types of parametric tests of differences1. Independent t-test
2. One-Way ANOVA
3. Paired t-test
4. Repeated Measures ANOVA
5. Analysis of covariance (ANCOVA)
6. MANOVA - 2Why use an Independent t-testTo see differences between 2 groups.
comparison of characteristics - 3Limitations of an Independent t-test-normally distributed data
-equal variances between groups
-independent of scores from one another - 4Why One-Way ANOVAdifferences between 2 or more groups
-IV has 2 or more levels, but only 1 DV. - 5Limitations of a One-Way ANOVA- normally distributed data
- equal variance between groups
-Independent of scores from one another
-3 or more groups will not tell you where the difference is (need post hoc testing) - 6Why Paired T-Test-see differences WITHIN same group over TIME
-pretest/posttest designs in which subjects act as their own control group. - 7limitations of a Paired T-Testnormally distributed data
- 8Why Repeated Measures ANOVA-differences among repeated measures on subjects WITHIN the same GROUP
-repeated measures design in which the IV has 2 or more levels AND subjects act as their own control
- factorial designs with more than 1IV but ONLY 1 DV - 9Limitations of a Repeated Measures ANOVAnormally distributed data
3 or more time points will not tell you where the difference is (need post hoc testing) - 10Why Analysis of covariance (ANCOVA)differences among 2 or more groups while controlling for variables
-designs where the IV has 2 or more levels, but only 1 DV - 11Limitations of an Analysis of covariance (ANCOVA)-normally distributed data
-Covariates should not be correlated linearly
-covariates can be nominal, interval or ratios - 12Why MANOVA-a difference in two or more outcomes among two or more groups
-Designs when the IV has 2 or more levels
-Factorial designs with more than one IV
-Use when there is MORE than one DV - 13Limitations for MANOVA-Normally distributed data
-Three or more groups will not tell you where difference is (need post hoc testing)
