Exam 6: Research Strategies and Validity.

A researcher who is studying methods of decreasing test anxiety decides to measure anxiety in a group of volunteers both before and after an experimental intervention.He finds that anxiety levels are lower after the intervention.However,when reviewing his results,the researcher notes that the first test occurred about a week before midterm exams and the second test occurred two weeks after the exams.This study appears to have a problem with ____.
