Question Description

For this assessment, you will use simulated historical data from a selection system. The data includes multiple predictor measures and a criterion measure. The predictors include two measures of job knowledge, Test1 and Test2, which have been designed to be equivalent measures of a required body of job knowledge; as well as work sample test results from two evaluators, SampleA and SampleB, working independently but under the same work sample protocol. The criterion measure is a valid and reliable composite measure of work performance, called PER. Each case in the data file corresponds to an applicant who was hired in the past year.

Additional files posted in a directory on the course site in Brightspace include the datafile THAw21.xlsx and a fillable form for your responses. Each of the following five numbered questions is worth 4 points, for a combined total of 20 points. Remember to use the form for your submission, and to submit to the labelled drop-box on the course site.

1. Report the mean, standard deviation, and intercorrelations of all the variables in the datafile.

2. Standardize the variable Test1, and report the mean and standard deviation of this new variable, which we will call Test1 s. What is the validity of Test1 ? What is the validity of Test1 s? Ensure that you report both the relevant correlation coefficients and their interpretations, from the applicable table in the text.

3. From Q1, report the correlation coefficient for the relationship between Test1 and Test2. What form of reliability is this? Based on the standards for interpretation provided in the text, what is the meaning of this result? How will you respond to this result, as an HR manager working within this system?

4. From Q1, report the correlation coefficient for the relationship between SampleA and SampleB. What form of reliability is this? Based on the standards for interpretation provided in the text, what is the meaning of this result? How will you respond to this result, as an HR manager working within this system?

5. Consider the validity coefficients that you provided in your response to Q1. Which predictor is the most valid, and which is the least valid?Ensure that you report both the relevant correlation coefficients and their interpretation, from the applicable table in the text. How will you respond to these results, as an HR manager working within this system?
