Mode Formula of Grouped Data
For determining the mode in case of data is grouped, simple observation does not help. We use a special formula to calculate the mode in case of grouped data is given.
Mode Formula of Grouped Data is as follows :
Mode = l + [(f1 – f0) / (2f1 – f0 – f2)] × h
where,
- l is the lower limit of the modal class.
- h is the size of the class interval,
- f1 is the frequency of the modal class,
- f0 is the frequency of the class preceding the modal class, and
- f2 is the frequency of the class succeeding the modal class.
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.
