Strengthening the Argument: Study Methods and Scores

Very Easy Critical Reasoning Strengthening Data Arguments

In a recent study, it was found that students who studied with friends scored an average of 15% higher on their math exams compared to those who studied alone. This indicates that studying with friends is more effective than studying alone. However, the researchers did not consider the fact that those who study with friends might already be higher-achieving students.

To strengthen the argument that studying with friends leads to better scores, which of the following pieces of information would be most helpful?

A survey showing that students who study with friends generally have a more positive attitude towards learning.

Information that the average study time for both groups was the same.

Data revealing that students studying with friends retained information better than those studying alone.

Statistics indicating that students who study alone were more likely to miss classes.
