A small firm has 10 employees. Here are their yearly salaries in thousands of pounds:
16, 16, 16, 16, 17, 18, 18, 19, 19, 45.
a) Calculate the mean, median and mode.
To find the mean: Add the salaries and divide by the number of employees.
To find the median: Make sure the salaries are in order of size. Find the middle salary.
To find the mode: Which salary do more employees get than any other?
b) Which of the mean, median or mode best represents the “average salary” of the employees.
Think about the mean: only one employee earns more than the mean so would it be sensible to use it to represent the average salary?
