Modus (EN)

Definition

The mode is the value that appears most frequently in a data collection. Unlike the mean and median, there can be multiple modes (bimodal or multimodal distributions) or no mode if all values occur with the same frequency. The mode is particularly useful for categorical data where arithmetic means are not possible, and it provides insight into the typical value of a variable.

Example

• In the data collection [1, 2, 2, 3, 4], the mode is 2
• In the data collection [1, 1, 2, 2, 3], there are two modes: 1 and 2 (bimodal)
• When analyzing favorite colors, the mode is the most frequently mentioned color

In Context

• Typically used together with mean and median to describe the central tendency of a distribution
• Related to: Median, Mean, Quantile, Variance
• Example applications: Market research, opinion polls, qualitative data analysis
