Reference no: EM13155558
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 given in the resource document
Currently, the same I/O psychologist must make a decision about which two applicants to hire for newly-created sales positions. There are 10 applicants for the two positions, who completed quantitative measures on the same predictors above.
In this assignment, you will perform the multiple regression analysis on the data from those hired two years ago. You will then use that information to make decisions regarding which of the current candidates should be hired..
1. Enter variables using the stepwise procedure.
2. Interpret the results and write the regression equation using the following format:
Y = (b1 x X1) + (b2 x X2) + (b3 x X3) + a, where a is the intercept, and the bs are regression coefficients.
1. In a statement of 300-400 words, describe what the data indicate about employee performance and coaching needs. Include the following in the statement:
2. A discussion of which of these employees may need coaching and which are performing at acceptable levels.
State the regression equation you wrote above, and use the equation computed and the data obtained from those hired two years ago to make a decision about which two individuals should be offered the current positions. Justify your decision in a statement of 300-400 words.
