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.
Prompt 1.
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.
Prompt 1.
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?
