Mode Calculator
Enter a list of numbers separated by commas or spaces and instantly find the mode (most frequent value), distribution type (unimodal, bimodal, or multimodal), and complete frequency table.
Mode Distribution Types
| Type | Definition | Example |
|---|---|---|
| Unimodal | One mode | {1, 2, 3, 3, 3, 4} → mode = 3 |
| Bimodal | Two modes | {1, 1, 2, 3, 3} → modes = 1, 3 |
| Multimodal | Three or more modes | {1, 1, 2, 2, 3, 3} → modes = 1, 2, 3 |
| No mode | All values equally frequent | {1, 2, 3, 4, 5} → no mode |

Frequently Asked Questions
What is mode?
The mode is the value that appears most frequently in a data set. For example, in {1, 2, 2, 3, 3, 3, 4, 5} the mode is 3 because it appears 3 times — more than any other value.
Can there be more than one mode?
Yes. A data set with one mode is unimodal, two modes is bimodal, and three or more is multimodal. For example, {1, 1, 2, 3, 3} has two modes (1 and 3) and is bimodal.
What if all values appear once?
If every value appears the same number of times, the data set has no mode. For example, {1, 2, 3, 4, 5} has no mode because each value appears exactly once.
When to use mode?
Use mode for categorical data (most popular color, most common shoe size), ordinal data, and when you want the most typical value. It is the only measure of central tendency that works with non-numeric data.
The mode is the only measure of central tendency that can be used with nominal (categorical) data.
