Mode
Grade 3-5
The value that appears most often in a data set. Mode is the only measure of center that works for non-numerical data, like favorite colors or names.
Definition
The value that appears most often in a data set. A set can have no mode, one mode, or multiple modes.
💡 Intuition
The mode is the most popular value - the one that shows up the most. If 5 kids pick pizza, 3 pick tacos, and 2 pick burgers, pizza is the mode because it's the favorite.
🎯 Core Idea
The mode is the most frequently occurring value. It is the only measure of center that applies to non-numerical (categorical) data.
