Mode Calculator
Find the mode of your dataset, the value that appears most frequently. This calculator identifies all modes, reports their frequency, and classifies the data as unimodal, bimodal, or multimodal.
The mode is one of the three primary measures of central tendency, alongside the mean and median. Unlike the mean, the mode is not affected by extreme values (outliers), and unlike the median, it identifies the most typical value based on frequency rather than position.
A dataset can have one mode (unimodal), two modes (bimodal), or more (multimodal). If every value occurs the same number of times, the dataset has no mode. Bimodal and multimodal distributions often indicate that the data comes from two or more distinct subpopulations.
The mode is especially useful for categorical data where the mean and median are not meaningful. For example, the most popular shoe size, the most common survey response, or the most frequent diagnosis in a medical study are all applications of the mode.
