Question

Problem Set 10.1: Correlational Studies

• Criterion: Determine if a correlation is the appropriate analysis for a study.

• Instruction: Answer this: Which of the following scenarios might be analyzed using a correlation?

a. The effectiveness of training A versus training B in raising skill level.

b. Minutes spent exercising per week and physical fitness score.

c. Income level and the number of visits to a financial planner.

d. Beer brand preference among college students.

Answer 1

From the above given scenarios, (b) and (c) can be analyzed using a correlation.

As in option (b), Minutes spent exercising per week and physical fitness score are quantitatively related. Thus, this relation can be established using correlation.

Similarly, in option (c), Income level and the number of visits to a financial planner are quantitatively related. So, relation can be established using correlation.

whereas options (a) and (d) are qualitatively, not quantitatively related. Thus, for these cases analysis using correlation will not be appropriate.
