LAB: Performing a Two-Way Repeated-Measures ANOVA
- What is the appropriate factorial notation for the design of this study (e.g., 3x3x2 Mixed design)?
- State the 3 alternative hypothesis for the study in terms of the effects or the IV's (Factors) on the DV:
Hypothesis 1:
Hypothesis 2:
Hypothesis 3:
- Complete the following means table including the marginal means:
- Complete the following based on your descriptives table from the SPSS output:
- How many participants are in the study?
- How many scores are in each factorial condition (cell)?
- Which factorial condition had the highest mean error rates?
- Which factorial condition had the most variability in error rates?
| DV =Error rate on grammatical reasoning test (%) | Independent Variable: Lighting | Marginal means for noise conditions | ||||||
| Dynamic lighting | Static lighting | |||||||
| Independent Variable: Noise | Low intelligibility | |||||||
| High intelligibility | ||||||||
| Marginal means for lighting conditions |
