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

Nebraska passing yards
Temperature at kickoff (Fahrenheit)
Conference game (non-conference = 0, conference = 1)
Home game (no = 0, yes = 1)
