A University Did a Study to Find Out Whether Having

question 36

Multiple Choice

A university did a study to find out whether having a part-time job is related to academic performance. The office surveyed 1,200 students on how many hours they worked per week and other information, including each student's grade-point average. The results showed that the more hours students worked at jobs, the lower their grades tended to be. The university concluded that working part-time causes students to have less time for schoolwork, which leads to lower grades. The BEST analysis of this conclusion is that the university is:

• A) correct in making a causal inference from their data because it had such a large sample.
• B) wrong to make a causal inference from its data because survey data of this sort do not allow causal inferences.
• C) correct in its conclusion because conducting a survey research study allowed the researchers to ask many research participants very specific question.
• D) wrong to make a causal inference from its data because those data were not collected using at least a quasi-experimental research design.
