**Mode**

The most frequently occurring value (or class) in data is called the mode.

- The mode is the most commonly appearing value in the data distribution.
- We can use mode as the measure of central tendency for both categorical and numerical variables.
- The data distribution can have more than one mode.

**Example**

The age in months of 15 Tiny Tots from a preschool is given in the table below. Compute Mode.

Let’s create a frequency distribution table for the above data.

Value |
24 |
36 |
37 |
38 |
39 |
40 |
41 |

Frequency |
1 | 3 | 4 | 2 | 2 | 2 | 1 |

- The value 37 appeared the max number of times (four times) in the data distribution.
- Hence,
**Mode = 37**

Types of Mode

Types of Mode

**Unimodal:**There is only one mode in the data distribution. For E.g., x = 1,2,2,3 (mode = 2).**Bimodal:**There are two modes in the data distribution. For E.g., x = 1,2,2,3,3,4 (mode = [2,3] ).**Trimodal:**There are three modes in the data distribution. For E.g., x = 1,2,2,3,3,4,4,5 (mode = [2,3,4] ).**Multimodal:**There are more than three modes in the data distribution. For E.g., x = 1,2,2,3,3,4,4,5,5,6 (mode = [2,3,4,5] ).

**Application of Mode**

A fashion retailer selling items like shoes, shirts, etc will have to manage inventory based on most selling sizes. The mode is the best statistic to be used in such instances; mean & median may not be of much use.

The mode is the only measure of central tendency that can be used for Categorical Variables.

**Practice Exercise 1**

Find the mode for the below histogram

**Practice Exercise 2**

A small startup has 10 employees including the founder members. The monthly salaries of all the employees are given in the table below. Find the mode salary.

Emp. No. | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |

Monthly Salary (k) | 90 | 80 | 18 | 18 | 17 | 16 | 16 | 16 | 15 | 14 |
