PSY-838 Quantitative Measures Data To carry out a validation study, an I/O psychologist is developing a regression equation from data collected from those hired two years ago. Specifically, the I/O psychologist is examining the relationship between extraversion, cognitive skills, and communication ability on sales performance (the dependent measure). The data are shown below.

There are 10 applicants for the position, who completed quantitative measures on the same predictors above. The data are shown below.
