Types of Mode in Statistics
Depending upon the number of modal solutions, mode is classified into the following categories:
- Unimodal
- Bimodal
- Trimodal
- Multimodal
Type | Definition | Example Data Set | Modes |
---|---|---|---|
Unimodal | When there is only one and only one mode in a dataset. | Set X = {1, 2, 2, 3, 6, 7, 7, 7, 8, 9} | Only 7 |
Bimodal | When there are two modes in the given data set. | Set A = {1, 1, 1, 3, 4, 4, 6, 6, 6} | 1 and 6 |
Trimodal | When there are three modes in the given data set. | Set A = {2, 2, 2, 3, 4, 4, 6, 6, 6, 7, 9, 9, 9} | 2, 6, and 9 |
Multimodal | When there are four or more modes in the given data set. | Set A = {1, 1, 1, 3, 4, 4, 6, 6, 6, 7, 9, 9, 9, 11, 11, 11} | 1, 6, 9, and 11 |
Note : A dataset without recurring values, however, lacks a mode.
Mode in Statistics | Definition, Formula and Examples
Mode is the most frequently occurring value in a given set of data. It is a measure of central tendency that is used in statistics.
In statistics, the mode is the number that comes the most frequently among a group of numbers. It is one of three measures of central tendency, alongside the mean and median. To determine the mode, count how frequently each number appears. The number that comes the most frequently is the mode. One disadvantage of using the mode as a measure of central tendency is that the data set can have no mode or multiple modes.
For example, if a set of numbers had the digits 1,2,2,3,3,3,4,4,5 then the mode would be 3.
Let’s learn the meaning and formula of mode in statistics with the help of solved examples.
