Mode

For a different type of requirements different central tendencies are used.

Mode tells us the number of observation which occurs more frequently. The observation which occurs most of the time is called the Mode of that group.

Example

If we have the observation of average temperature in New Delhi for 12 months then find the month in which it has the maximum average temperature? What is the mode of the given observation?

MonthAverage Temperature
January18
February22
March24

July27
August27

October25
November21
December19

Solution

As you can see that the maximum average temperature is in the month of June.

Its mode will be 27 as it occurs more frequently i.e. three times.

Mode of a Large Number of Observations

If the number of observations is very large then we can convert the data in the tabular form using frequencies and tally marks. Then it will be easy to find the mode of the given data.

So you can check the number of observation which has a large number of frequency is the mode of that group.

Example
