C) multiple regression.
D) nonlinear correlation.

Question

Quizplus · Accepted Answer

Predicting an individual's IQ score from two variables, socioeconomic status and education level, requires the use of multiple regression. Bivariate regression is used when only one predictor is involved, simple linear regression is used when only one predictor is involved and it assumes a linear relationship between variables, and nonlinear correlation is used when the variables in question do not have a linear relationship. However, since we are using two predictors (socioeconomic status and education level), and we want to account for their combined effects on IQ score, we need to use multiple regression.
