How average calculator works
This calculator computes three common measures of central tendency. The mean is the sum of all values divided by the count. The median is the middle value when the numbers are sorted; if there is an even count, it is the average of the two middle values. The mode is the most frequently occurring value.
Enter your numbers separated by commas (for example: 2, 4, 4, 6, 8). Select which measure you want. For the mode, if all values appear equally often, the calculator reports no mode. If multiple values tie for most frequent, all are returned.
All calculation happens in your browser. The input is parsed as numbers, so you can use decimals and negative values.
Frequently asked questions
What is the difference between mean, median, and mode?
The mean is the arithmetic average (sum divided by count). The median is the middle value when sorted. The mode is the most frequently occurring value. They can give different results for the same data set.
How is the median calculated with an even number of values?
When there is an even count, the median is the average of the two middle values. For example, the median of 1, 3, 5, 7 is (3 + 5) / 2 = 4.
What if there is no mode?
If every value in the set appears the same number of times (all unique, for instance), there is no mode. The calculator reports this rather than returning a value.
Can I use decimals and negative numbers?
Yes. The calculator accepts any numeric values, including decimals and negatives. Enter them separated by commas.
