About this tool
Paste a comma-separated list of numbers and the tool summarises the whole set. It finds the mean, the middle value, the most frequent value, the spread from smallest to largest, and the population standard deviation, which measures how far the numbers typically sit from the mean.
Frequently asked questions
What is the difference between mean and median?
The mean is the total divided by the count, while the median is the middle value when the numbers are sorted. The median is less affected by one very large or very small value.
What does standard deviation tell me?
It tells you how spread out the numbers are. A small value means the numbers cluster near the mean; a large value means they are more scattered.
