how to calculate mode give me an example
Answers
Answer:
A mode is defined as the value that has a higher frequency in a given set of values. It is the value that appears the most number of times.
Example: In the given set of data: 2, 4, 5, 5, 6, 7, the mode of the data set is 5 since it has appeared in the set twice.
Statistics deals with the presentation, collection and analysis of data and information for a particular purpose. To represent this data, we use tables, graphs, pie-charts, bar graphs, pictorial representation and so on. After the proper organization of the data, it must be further analyzed to infer some useful information from it.
For this purpose, frequently in statistics, we tend to represent a set of data by a representative value which would roughly define the entire collection of data. This representative value is known as the measure of central tendency. By the name itself, it suggests that it is a value around which the data is centred. These measures of central tendency allow us to create a statistical summary of the vast organized data. One such measure of central tendency is the mode of data.
Example: In the given set of data: 2, 4, 5, 5, 6, 7, the mode of the data set is 5 since it has appeared in the set twice.
Bimodal, Trimodal & Multimodal (More than one mode)
When there are two modes in a data set, then the set is called bimodal
For example, The mode of Set A = {2,2,2,3,4,4,5,5,5} is 2 and 5, because both 2 and 5 is repeated three times in the given set.
When there are three modes in a data set, then the set is called trimodal
For example, the mode of set A = {2,2,2,3,4,4,5,5,5,7,8,8,8} is 2, 5 and 8
When there are four or more modes in a data set, then the set is called multimodal
