Final answer:
Greg uses a Forced Distribution method for categorizing his mechanics. The department store manager utilizes Cluster sampling for employee interviews, and athletic ability classification is done using an Ordinal scale. The correct option is A.
Step-by-step explanation:
When Greg, the manager at a car repair shop, is required to categorize his mechanics into three groups as above average, average, and below average, he is employing the Forced Distribution method.
A Forced Distribution is a performance management system that assumes employee performance levels conform to a bell curve and requires managers to evaluate their workforce accordingly. This practice is often compared to how a teacher might grade on a curve, where certain quotas of high and low grades are predetermined even if actual performance varies.
The question related to the manager of a department store conducting interviews with employees from four randomly selected departments is utilizing a Cluster survey design. Cluster sampling involves selecting groups or 'clusters' of participants, where the groups are naturally occurring and represent the population as a whole.
For the school soccer players' athletic ability classification, the type of measure scale being used is Ordinal, as the categories imply a specific order or ranking without indicating the precise differences in performance levels between them.
Hence, Option A is correct.
