Dr. Moynihan conducts a study examining the relationship between the number of panic attacks a person experienced in the past month, the number of nightmares experienced in the past month, and people's levels of neuroticism (a personality trait characterized by instability, anxiety, and worry). She collects a convenience sample of 50 community college students (25 males, 25 females). Below are her findings. < A—number of panic attacks in the past month and neuroticism: r = -.03, not sig. < B—number of panic attacks in the past month and number of nightmares in the past month: r = -.14 (p = .05) < C—number of nightmares in the past month and neuroticism: r = .48 (p = .003) Dr. Moynihan data two outliers. What does this mean and what should be done? What aspect of Dr. Moynihan's study makes her findings especially susceptible to outliers? Which validity is threatened and why (construct, statistical, internal or external)?
