Frequently Asked Questions
What is the difference between mean, median and mode?
The mean is the average, the median is the middle value when sorted, and the mode is the value that appears most often. Together they describe the center of your data in different ways.
Should I use sample or population standard deviation?
Use the sample standard deviation when your numbers are a sample drawn from a larger group, and the population version when they are the whole group. The sample version divides by one less than the count.
What does standard deviation tell me?
It measures how spread out the values are around the mean. A small standard deviation means the numbers cluster close to the average, while a large one means they are more scattered.
What if there is no mode?
If every value appears the same number of times, there is no mode and the tool says so. If several values tie for most common, it lists all of them.
Is my data sent anywhere?
No. Everything runs in your browser. The numbers you paste never leave your computer and the tool works offline once loaded.
How many numbers can I enter?
You can paste large lists. The tool handles hundreds of values quickly, and the chart groups them into bins so the distribution stays readable.
