Multiple regression can help eliminate internal validity problems by ___________ potential third variables. It also sets a _____________ variable that acts as the independent variable, or the variable that will influence another variable; and a ___________ variable that acts as a dependent variable, or the variable that is hypothesized to be affected by another variable. Effect sizes in multiple-regression analyses are represented by ___________, which is a standardized effect size, and ____________, which is an unstandardized effect size.

Answer:controlling forpredictor criterionbetab Step-by-step explanation:Multiple regression can help eliminate internal validity problems by controlling for potential third variables. It also sets a predictor variable that acts as the independent variable, or the variable that will influence another variable; and a criterion variable that acts as a dependent variable, or the variable that is hypothesized to be affected by another variable. Effect size in multiple-regression analyses are represented by beta, which is a standardized effect size, and b which is an unstandardized effect size
