**Mode | What is mode?**

The

**mode**of a set of data is the value with the highest frequency. A distribution having two modes is called**bimodal**. The mode of a set of data is denoted by**M**._{o}********************

**10 Math Problems** officially announces the release of **Quick Math Solver** and **10 Math Problems**, **Apps** on **Google Play Store** for students around the world.

__Mode of discrete data__**:**

__Mode of discrete data__

In the case of discrete data, mode can be
found by inspection, i.e. just by taking an item with highest frequency.

*Example 1: Find the mode for the following distribution.*

*25, 18, 20, 18, 22, 18, 20, 18, 20*

*Solution:*

*Here,*

*Arranging the data in ascending order:*

*18, 18, 18, 18, 20, 20, 20, 22, 25*

*Here, 18 has the highest frequency.*

*∴*

*Mode = 18.*###
__Mode of grouped and
continuous data__**:**

__Mode of grouped and continuous data__

In the case of grouped and continuous data, the class with highest
frequency is observed and it is taken as the modal class. Then by using
following formula, mode can be computed.

Alternatively,
mode can also be computed by the following empirical relation.

Mode = 3 Median – 2 Mean

*Example 2: Compute the mode from the data giveb below,*

Age in years |
3-6 |
6-9 |
9-12 |
12-15 |
15-18 |
18-21 |

No. of pupils |
15 |
17 |
22 |
16 |
12 |
3 |

*Solution:*

*Here,*

*Here, 22 is the highest frequency and its corresponding class is 9-12*

*∴*

*Model class = 9-12*

*So, the required mode is 10.36*
