A researcher predicts whether a student will pass a course (1 = pass, 0 = fail) from hours studied and test anxiety. In SPSS Logistic Regression, the output shows for HoursStudied: B = 0.40, S.E. = 0.10, Wald = 16.00, p < .001, Exp(B) = 1.49. Which interpretation is correct (holding anxiety constant)?
A
Each additional hour studied increases the probability of passing by 0.40 (40%).
B
Each additional hour studied multiplies the odds of passing by 1.49 (about a 49% increase in odds).
C
Each additional hour studied increases the odds of passing by 0.40 (40%).
D
Hours studied has no meaningful effect because logistic regression cannot interpret slopes like regression does.
