Mode Calculator

The Mode Calculator calculates exact, real-time domain outputs in active voice. The Mode Calculator tabulates exact occurrence frequencies for every unique value in your dataset, identifying whether the distribution has a single mode (unimodal), two modes (bimodal), multiple modes (multimodal), or no mode (uniform).

Mode Calculator Input Parameters & Defaults

Dataset Values4, 7, 9, 7, 12, 4, 7, 15Comma-separated numbers.

Mode Calculator Mathematical Formula

\text{Mode} = \arg\max_{x} f(x)

Mode Calculator Worked Example

Dataset: 4, 7, 9, 7, 12, 4, 7, 15.

  1. Frequency count: 7 appears 3 times; 4 appears 2 times; 9, 12, 15 appear 1 time each.
  2. Mode = 7 (Unimodal with frequency 3, representing 37.5% of observations).

Mode is the only measure of central tendency that works on nominal/categorical data as well as discrete inventory sizes (like shoe sizes).

Mode Calculator Frequently Asked Questions

Q: Can a dataset have no mode?

Yes. If every value in the dataset occurs the exact same number of times (for example, each number appears once), the distribution has no mode.
