About This Tool
The Average Calculator computes the mean, median, mode, range, sum and count from any list of numbers — enter one number per line or separate with commas.
Frequently Asked Questions
What is the difference between mean and median?
The mean is the sum of all values divided by the count. The median is the middle value when sorted. The median is less affected by extreme outliers.
What is mode?
The mode is the value (or values) that appear most frequently in the data set. A set can have multiple modes or none if all values are unique.
Is there a limit to how many numbers I can enter?
The tool handles any reasonable number of values that fit in the input box. Performance may slow for very large data sets.
