Average Calculator — Mean, Median, Mode and Range
Paste a list of numbers to get the mean, median, mode, range, sum and count, plus weighted, geometric and harmonic averages and the sorted list.
| # | Value |
|---|---|
| 1 | 12 |
| 2 | 15 |
| 3 | 15 |
| 4 | 18 |
| 5 | 22 |
| 6 | 30 |
"Average" usually means the mean, but the median and the mode answer the same question in different ways, and the right one depends on your data. This average calculator gives all three at once for any list of numbers — test scores, prices, times, measurements — together with the range, sum, count, minimum and maximum. Add weights for a weighted average, and for positive data it also shows the geometric and harmonic means.
How to use this tool
- Paste or type your numbers, separated by spaces, commas or new lines.
- For a weighted average (grades by credit hours, prices by quantity), enter one weight per number.
- Read the mean, median, mode and range; the table lists the values in order.
- For spread, open the standard deviation calculator with the same list.
Formula
Mean = Σx ÷ n · Median = middle value of the sorted list · Weighted mean = Σ(w·x) ÷ Σw
With an even count the median is the mean of the two middle values. The mode is the value that occurs most often; there can be several, or none when every value appears equally often. The geometric mean is the n-th root of the product (useful for growth rates) and the harmonic mean is n ÷ Σ(1/x) (useful for averaging speeds or rates).
Example
For 12, 15, 15, 18, 22, 30 the sum is 112 and the count 6, so the mean is 18.67. Sorted, the middle values are 15 and 18, so the median is 16.5. The mode is 15 (it appears twice) and the range is 30 − 12 = 18.
Frequently asked questions
Mean or median — which should I use?
The median is better when a few extreme values pull the mean, as with house prices or incomes. The mean uses every value and is the usual choice for scores and measurements without big outliers.
How do I average percentages or speeds?
Weight them. The average of 50% of 10 items and 90% of 30 items is not 70%; enter 50 and 90 with weights 10 and 30 to get 80%. For average speed over equal distances, use the harmonic mean.
Why does 1,234 come out as two numbers?
Commas separate values here. Type large numbers without thousands separators (1234) or put each number on its own line.
