You run a binary logistic regression in SPSS predicting whether a customer will BUY a product (0 = no, 1 = yes) from whether they saw an ad (0 = no ad, 1 = ad). SPSS reports for the predictor: B = 0.80, Exp(B) = 2.23, p = .01. Which interpretation is best?
A
Seeing the ad increases the probability of buying by 0.80 (80 percentage points)
B
Seeing the ad makes a customer 2.23 times more likely to buy, and the effect is statistically significant
C
Seeing the ad increases the odds of buying by a factor of 2.23, and the effect is statistically significant
D
Seeing the ad causes customers to buy 2.23 more products on average
