Discussion (WK1) Question 1: When is the mean the best measure of central tendency? When is the median the best measure of central tendency? Explain. Mean is the best measure of central tendency when we have raw data or frequency data with closed end classes. Moreover, mean is appropriate measure if the data doesn’t have huge deviation or is symmetrical in distribution. Median is the best measure of central tendency in case of frequency data with open end classes. It is also appropriate to be used in case of data with huge deviation. Reference: th Ed. McGraw-Hill Irwin. 2011: CH14, Pages 64 & 73. Questions 2: A researcher has determined that the distribution of annual salaries of NBA players is bell-shaped and symmetrical about the mean salary; do you think that introducing Michael Jordan’s last annual salary of more than $30 million would skew this distribution? Explain why or why not. What would be the best measure of central tendency for this distribution? Explain
