How to calculate an average
Provide a number list and review the descriptive statistics returned.
Enter your numbers
Type at least one finite number, separating values with commas, spaces, semicolons, or line breaks.
Review the mean
The arithmetic mean is calculated by dividing the total sum by the number of values.
Compare the statistics
Use the median, mode, range, count, and sum to understand the centre and spread of the data.
Frequently Asked Questions
How is the arithmetic mean calculated?
Add all values and divide by their count: <strong>mean = sum ÷ count</strong>.
What is the median?
Sort the values and take the middle one. With an even count, average the two middle values.
What is the mode?
The mode is the value or values that occur most often. If every value occurs once, there is no mode.
What does the range show?
The range measures the spread from the smallest to the largest value: <strong>maximum − minimum</strong>.
How many numbers can I enter?
Enter a practical list of finite numbers separated by the supported delimiters. The calculator processes the list in your browser.
Does the order of numbers matter?
No. The mean, median, mode, and range are based on the values, not the order in which they are entered.
Can the average be a decimal?
Yes. The mean and median can be decimal values even when every input is a whole number.
