A therapist believes that teaching anxious clients group interaction skills can lessen their anxiety. She gives an anxiety test, chooses the 10% most anxious people, and then teaches them group interaction skills. On giving them a second anxiety test she discovers that their anxiety is significantly lower. If she concludes that the teaching has caused lessened anxiety she is ignoring statistical regression as a potential threat to internal validity.
