Answer:
A commonly used measure of central tendency, apart from Arithmetic Mean and Median, is Mode. The fundamental definition of Mode is the most frequently occurring value of the variable, i.e. that value of the variable which occurs the maximum number of times in a data set. If all values of the variable occur equal number of times, then mode is undefined. However, if more than one value of the variable has maximum frequency, then mode is defined, but not unique. It finds use in the field of business. For example, most shoe stores prefer to stock the “most popular size”, i.e. the most common size which is purchased most usually by the customers. Strictly speaking, the above definition of mode is applicable to discrete variables only. For calculating mode in case of a frequency distribution of a continuous variable we will use a formula. Mode is usually denoted by the symbol
