Expression of Ideas practice question

While researching a topic, a student has taken the following notes: - A study compared two teaching methods across 20 classes. - Classes taught with method A scored 5 points higher on average. - Teachers chose which method to use; classes were not assigned randomly. - Method A was chosen mostly by experienced teachers.

The student wants to present the study's result while acknowledging a limitation. Which choice most effectively uses relevant information from the notes to accomplish this goal?

  3. C. Method A raises scores by 5 points.
  4. D. Experienced teachers are more effective with method B.
