How to find the average
The mean (average) is the sum of all numbers divided by how many there are. The median is the middle value when sorted, and the mode is the value that appears most often.
Frequently asked questions
How do I calculate the average?
Add all the numbers together, then divide by how many numbers there are. For 10, 20, 30 the average is (10+20+30)/3 = 20.
What's the difference between mean and median?
The mean is affected by extreme values; the median (middle value) is not, so median can be more representative for skewed data.
What if there is more than one mode?
If several values tie for most frequent, they're all modes — the data is multimodal.
