An educational psychologist conducted a study to investigate whether there is a difference in self-reported exam anxiety depending on the preparation method used. They compared two groups of students preparing for their final exams: the first group practiced mindfulness meditation daily (Mindfulness group), while the second group followed their standard study schedule (Traditional group).
Participants rated their perceived anxiety level on a scale of 1 to 10, with 10 indicating extreme anxiety.
