How do I examine correlations of all variables (1 DV & 5 IV) and summarize their relationship? <br/>I also want to know how to run simultaneous multiple regression to examine predictors of math achievement. <br/>I figured our how to "control" for a variable for question 1c (see attached file) but wondered if the hierarchical regression would be very different between the earlier outputs and this one. <br/>How do I figure out how to do a final regression equation? <br/>I am very confused! <br/>S
Write down the regression equation and state the R-squared value and the standard error and explain what they mean with respect to the data.
