In the table below, what does the beta for predictor variable proportion of students eligible for free mean? Multiple-Regression Results from a Study Predicting Behavior Problems from Recess Time and Family Income Criterion (dependent) variable: Classroom behavior problems Predictor (independent) variables Beta Minutes of recess -0.06 Proportion of students eligible for free lunch 0.10 Sig * * Note: Data are fabricated, based on results if the researchers had used only two predictor variables. *p< .001. As proportion of students eligible for free lunch increases, behavior problems decrease when the number of minutes of recess is held constant. As proportion of students eligible for free lunch increases, behavior problems increase when the number of minutes of recess is held constant. As proportion of students eligible for free lunch increases, behavior problems increase There is no significant relationship between this predictor and outcome of classroom behavior problems
