1.The Pearson product-moment correlation
2.Bivariate regression
3.Multivariate regression
4.Analysis of variance
A1, 2 and 3 only
B2 and 3 only ✓ Correct
C2, 3 and 4 only
D1 and 4 only
Correct answer: (B) 2 and 3 only
Explanation
Predicting an outcome variable from one or more variables uses regression, so bivariate and multivariate regression are correct.
Bivariate regression predicts an outcome from a single predictor variable.
Multivariate regression predicts an outcome from several predictors together.
The Pearson product-moment correlation only measures association, it does not predict values.
Analysis of variance compares group means rather than predicting a continuous outcome.
Regression yields an equation whose coefficients quantify each predictor's effect.
