RH1: Model Summary
| R | R² | F | df1, df2 | p | Does the model work? | |
|---|---|---|---|---|---|---|
| Model Summary | , |
RH1: Predictor Results
Significance Key:
- ns = p > .05 (not significant)
- * = p < .05
- ** = p < .01
- *** = p < .001
Result Categories:
- a = Neither r nor b significant
- b = r & b both significant & same sign
- c = r significant but not b
- d = suppressor effect
| Predictor | Type | r | r sig | b | b sig | Result |
