๐งฎ Mean Median Mode Range Calculator
Mean, median, mode and range are the four numbers every dataset summary starts with: the average, the middle value, the most frequent value and the span from smallest to largest. Together they sketch the shape of your data in seconds.
Watch how the mean and median disagree โ when a few extreme values drag the mean away from the median, your data is skewed and the median is the fairer โtypicalโ value.

Frequently asked questions
What does this calculator compute?
It computes the four core summary numbers of any dataset: the mean average, the median middle value, the mode most frequent value, and the range from the smallest to the largest value.
Can you show a worked example?
For 1, 2, 3, 4, 5 the mean is 3, the median is 3, there is no mode because every value appears once, and the range is 4.
When should I trust the median over the mean?
When a few extreme values skew the picture, like one billionaire in a salary survey. The median resists outliers because it only cares about the middle position, while the mean gets dragged toward the extreme.
What does the range tell me?
The range is the quickest possible measure of spread: max minus min. It is handy but fragile, since a single outlier stretches it, so pair it with the standard deviation for a fuller view.
