Example 2

medium
A shoe shop records sizes sold in one day: 6, 7, 8, 7, 9, 8, 7, 10, 8, 6. Is this data unimodal, bimodal, or multimodal?

Solution

  1. 1
    Step 1: Frequencies — 6: 2, 7: 3, 8: 3, 9: 1, 10: 1.
  2. 2
    Step 2: Both size 7 and size 8 appear 3 times, tied for highest frequency.
  3. 3
    Step 3: Two modes means the data is bimodal.

Answer

The data is bimodal with modes 7 and 8.
Data can have more than one mode. Bimodal data has two values tied for highest frequency, which can indicate two distinct popular groups in the data.

About Mode

The mode is the value that appears most often in a data set. A set can have no mode (all values appear equally), one mode (unimodal), or multiple modes (bimodal or multimodal). It is the only measure of center that works for categorical data.
