Question:
A researcher is comparing patients with high medication compliance versus those with low medication compliance in an outpatient psychiatric day program utilizing the Hamilton Anxiety Rating Scale (HAM-A), which has 14 items scored on a scale of 1–4. A higher score on the HAM-A indicates higher levels of anxiety. After collecting the data, she determines the scores obtained in both groups are normally distributed. In the low-compliance group, the mean score is 24 and the standard deviation is 2. In the high-compliance group, the mean score is 16 and the standard deviation is 1.5.
If instead of finding a normal distribution in the low compliance group the researcher discovers there are three individuals with scores that are substantially higher than the rest of the group, what type of skew would these outliers cause?
