How it works
Mean = Σ ÷ n. Median = middle of sorted data (avg of two middles if even). Mode = most frequent.
Example: [1,2,2,3,4,100] → mean 18.67, median 2.5, mode 2.
Frequently Asked Questions
What is the mode when no value repeats?
If every value appears once, there is no mode. The calculator shows 'none' in that case.
Can a dataset have two modes?
Yes. If two values appear equally often, the dataset is bimodal and both are shown.
When should I use median instead of mean?
Use the median when data is skewed by outliers, such as salaries or house prices, where a few extreme values distort the mean.
How is the range calculated?
Range = maximum − minimum. It measures spread in the data's own units but a single extreme outlier can inflate it.
