Advantages of mode, Applied Statistics
By definition, mode is the most typical or representative value of a distribution. Hence, when we talk of modal wage, modal size of shoe or modal size of family it is this average that we refer to. The mode is a measure which actually does indicate what many people incorrectly believe the arithmetic mean indicates. The mode is the most frequently occurring value. If the modal wage in a factory is Rs.2,000 then more workers receive Rs.2,000 than any other wage. This is what many believe the “average” wage always indicates, but actually such a meaning is indicated only if the average used is the mode.
It is not affected by extremely large or small items. For example, the mode of values 1, 4, 4 and 10 is 4 and the mode of values 1, 4, 4 and 1,000 is also 4.
Its value can be determined in open-end distributions without ascertaining the class limits.
It can be used to describe qualitative phenomenon. For example, if we want to compare the consumer preferences for different types of products, say, soap, toothpastes, etc. or different media of advertising we should complete the modal preferences expressed by different groups of people.
The value of mode can also be determined graphically, whereas the value of mean cannot be graphically ascertained.
