question 2

Essay

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)

-Imagine that Dr.Moynihan finds two outliers.These two people report a very high number of nightmares in the past month and have very high scores on neuroticism.Why should Dr.Moynihan be worried about the presence of these two outliers?
