Sample 1: {$30, $25, $10, $25, $10} and Sample 2: {$5, $60, $10, $30, $50}
(a) Calculate the mean and the median of each sample.
(b) Which sample has the least spread among its data values? Which sample has the least deviations from the mean among its values?
(c) A third sample was obtained: {$30, $25, $20, $20, $25}. Which data set in Part (a) has measures of center that align more closely with the mean and the median of the new sample? Based on the three samples, which sample is least representative of the population?
