A group of recent marketing graduates from a small liberal arts university have jobs ranging from selling shoes at $18,000/yr. to playing professional basketball at $1.5 million/yr. Current salaries for the 22 graduates are (in $000): 24, 20, 32, 36, 18, 28, 42, 37, 20, 27, 52, 31, 45, 33, 20, 1500, 23, 38, 27, 31, 36, 40. What is the mean salary for these graduates? Suppose the university wished to publish a brochure for prospective students, and include some indication of the average salary of recent graduates in various disciplines. Compute the average that best represents the central tendency of the data on marketing graduates. Explain your choice of one average over other averages for the data. Is the distribution symmetrical? Why or why not?
