### Introduction

Mode is defined as the value or the digit having the larger number of occurrences or frequency in the given set of data. It is the value that occurs the most number of times.

Eg – 2, 3, 5, 5, 6, 9, here the mode of the given set of data will be 5  as its frequency is higher in comparison to other numbers. It has appeared twice on the given set of data.

### Important Concepts

Bimodal – If in the given data set, we have the two modes, then we can call it the Bimodal Mode.

Eg  = { 2 , 2 , 2 , 3 , 4, 4 , 4 , 5 , 5 }

Here, in the above set, we have 2 and 4 coming three times with the largest frequency in the given order. Hence this is the answer.

Trimodal – If in the given data set, we have the three modes, then we can call it the Trimodal Mode.

Eg  = { 2 , 2 , 2 , 3, 3 , 3 , 4 , 4 , 5 , 5 , 5 , 6, 6}

Here, in the above set, we have 2, 3, and 5 coming three times with the largest frequency in the given order. Hence this is the answer.

Multimodal – If in the given data set, we have four or more modes, then we can call it the Multimodal Mode.
