About the Average Calculator
The average calculator finds the mean, median and mode of a list of numbers. The mean is the sum divided by the count, the median is the middle value once the numbers are sorted, and the mode is the value that appears most often. Comparing them tells you about the shape of your data: when a few very large or small values pull the mean away from the median, the median is usually the better description of a typical value. Paste numbers separated by commas or spaces.
How to use it
- 1Type or paste your numbers, separated by commas or spaces.
- 2Press Calculate to see the mean, median, mode, count and sum.
Worked example
for 4, 8, 15, 16, 23, 42 the sum is 108 and the mean is 108 ÷ 6 = 18. The median is the average of the two middle values, (15 + 16) ÷ 2 = 15.5. No value repeats, so there is no mode.
How it works
Definitions
- Mean: the sum divided by the count
- Median: the middle value when sorted
- Mode: the most frequent value(s)
Who it is for
Students, teachers, analysts and anyone summarising a set of numbers.
Why it helps
Seeing mean, median and mode together shows whether outliers are distorting the average.
Common use cases
- Averaging test scores or grades
- Summarising survey answers
- Finding a typical value in skewed data such as house prices
Frequently asked questions
A:If no value repeats, the mode is reported as None.
A:Use commas, spaces, or new lines between values.
