Refer to the Journal of Medical Ethics (Vol. 32, 2006) study of physicians' use of ethics consultation, Exercise 2.68. In addition to length of time in practice (i.e., years of experience), the researchers also measured the amount of exposure to ethics in medical school (number of hours) for the sample of 118 physicians.
a. Use data from the accompanying file to create a scatter plot for these two variables. Plot years of experience on the vertical axis and amount of exposure to ethics in medical school on the horizontal axis. Comment on the strength of the association between these two variables.
b. Conduct an outlier analysis of the data for the variable amount of exposure to ethics in medical school. Identify the highly suspect outlier in the data set.
c. Remove the outlier, part b, from the data set and re-create the scatter plot of part a. What do you observe?
