Question

The following is a dataset of salaries for a company in thousands). Find the mean and median and determine if the meanor median is the better measure of central tendency.

Answer 1

Answer:

Mean = 80, Median = 92

Mean is the better measure of central tendency

Explanation:

Given the following dataset

11, 87, 85, 95, 92, 93, 97

Find the mean

Mean = sum of data/sample size

Mean = 11+87+85+95+92+93+97/7

Mean = 560/7

Mean = 80

Median is the value of middle after re-arranging either in ascending or descending order

Rearrange

11, 85, 87), 92, (93, 95, 97

Since the value at the middle is 92, hence the median is 92

out of the measure of central tendency, mean is better than median

Mean = 80, Median = 92

Mean is the better measure of central tendency
