Mode Calculator
Find the mode — the most frequently occurring value(s) — of a data set, with the frequency and whether the data are unimodal, bimodal or have no mode.
How it works
Mode = the value(s) that occur most often · a data set may have one, several, or no mode
The mode is the value that appears most frequently in a data set — the only measure of central tendency that also works for categories and non-numeric labels. A set can be unimodal (one clear peak), bimodal or multimodal (several values tie for most frequent), or have no mode at all when every value occurs the same number of times. Unlike the mean and median, the mode is unaffected by how extreme the other values are.
Worked example
In 4, 7, 7, 2, 9, 7, 4, 5 the value 7 appears three times, more than any other, so the mode is 7 and the set is unimodal. If 4 also appeared three times, the set would be bimodal with modes 4 and 7.

Frequently asked questions
Can a data set have more than one mode?
Yes. When two or more values tie for the highest frequency the set is bimodal (two modes) or multimodal (more than two). This calculator lists every value that shares the top frequency.
When is the mode more useful than the mean?
The mode is best for categorical data (most common shoe size, favourite colour) and for spotting the most typical value in skewed data. The mean can land on a value that never actually occurs, whereas the mode is always a real data point.
What does "no mode" mean?
It means no value repeats — every observation occurs exactly once, so none is more frequent than the others. Such a data set is described as having no mode.
