Please access the Excel file for this assignment and answer the
following questions:
Look at the variables across the top row: Applicant ID #,
Initial Interview Score, Physical Ability Test Score,
Unstructured Interview Score, Job Performance Score, Guest
Satisfaction Score, and Absenteeism (Days).
a. Identify whether each variable is nominal, ordinal,
interval, or ratio. (7 points) Please justify your response

for each variable). (7 points)
b. Suppose that you rank order the candidates from best to

Currently, GTS uses the physical ability test, the initial
interview, and the manager unstructured interview to choose
candidates that they think will ultimately perform well,
contribute to guest satisfaction, and come to work when
scheduled.
a. List the predictors. (3) Why are these considered
predictors instead of criteria? (2)
b. Which variables are criteria? (3) Why are these
considered criteria instead of predictors? (2)
Using the "Physical Ability Data" data, calculate and interpret
