Different kinds of average
- Mean: the sum of all the numbers divided by how many there are. It's what people usually call the average.
- Median: the middle value once the numbers are sorted (with an even count, the mean of the two middle values).
- Mode: the value that appears most often. There can be more than one, or none.
- Range: the difference between the largest and the smallest value.
The formula
Mean = sum of the values ÷ number of values
Worked example
The numbers are 7, 8, 8, 9, and 10.
- Sum: 7 + 8 + 8 + 9 + 10 = 42. Mean: 42 ÷ 5 = 8.4.
- Median: the middle of 7, 8, 8, 9, 10 is 8.
- Mode: 8 appears twice, so the mode is 8. Range: 10 − 7 = 3.
Frequently asked questions
What's the difference between the mean and the median?
The mean adds up all the numbers and divides by how many there are. The median is the middle number once they are sorted. A single very large or very small value can move the mean a lot, but barely changes the median.
Can I paste numbers separated by commas?
Yes. "10,20,30" counts as three numbers, which is handy when you paste from a spreadsheet or a CSV file. Commas that form thousands, like 1,000 or 12,345,678, are read as part of the number.
How do I work out a weighted average?
Multiply each value by its weight, add the results, and divide by the sum of the weights. For example, grades of 8 (worth 30%) and 6 (worth 70%) average 8 × 0.3 + 6 × 0.7 = 6.6.
