Question

Including multiple predictors in one analysis ______.
A) guarantees significant results
B) is less accurate than using only one predictor 
C) offers no real research advantage
D) should increase the amount of explained variance in the criterion

Quizplus · Accepted Answer

Including multiple predictors in one analysis should increase the amount of explained variance in the criterion. However, it does not guarantee significant results and can actually lead to less accurate results if the predictors are not related to the criterion variable. Additionally, using multiple predictors allows for the examination of the unique contribution of each predictor to the criterion variable, offering a significant research advantage.
