Document Summary

Advanced correlational strategies: linear regression, linear relationships. Regression analysis: ability to predict scores on one variable from 1+ other variables: goal = develop regression equation from which we can predict scores on one variable. "simultaneous multiple regression: stepwise multiple regression -- based on strength of ability to predict criterion variable using pearson correlation (r) Add further predictor variables given that first predictor variable is already in the equation. Based on ability to predict unique variance in the outcome variable (variance not already predicted by predictor variables already in equation: hierarchical multiple regression -- order predetermined by the researcher. Partials out/removes the effects of the predictor variables entered in earlier steps.
