Frequently Asked Questions

How do you find the arithmetic mean?

Add all the numbers together and divide the sum by the count. For example, the mean of 4, 8, 12 = (4+8+12)/3 = 24/3 = 8.

What is the difference between the mean and the median?

The mean is the sum divided by the count. The median is the middle value in a sorted list. For skewed data, the median is more representative.

Where is the arithmetic mean used?

At school: grade point average. In statistics: average salary, temperature, height. In sports: average score.
