Mode
Definition
The value that appears most frequently in a data set. A data set can be unimodal (one mode), bimodal (two modes), or multimodal (more than two modes). It is the only measure of central tendency applicable to qualitative (categorical) data.
Example
"Data: 5, 8, 8, 9, 10, 10, 10. Mode = 10 (appears 3 times). In a shoe store, Mode helps identify the most popular shoe size to stock."
