Previously we have discussed about scientific notation and rational numbers and In today's session we are going to discuss about Mode which comes under 12th state board syllabus tamilnadu, It is the part of statistics that is used to define or find the value among the set of the data that occurs most frequently. Statistics mode is used to define or find the value of a distribution or a raw data set that have the maximum frequency. Thus the mode of distribution is that value of the variable around which the values of the variable are clustered densely.
For computation of mode of a series of individual operation, we first convert it into the discrete series frequency distribution by preparing the frequency table .From the frequency table we can identify the value having the maximum frequency .The value of the variable obtained is the mode or the modal value.
Let us take some example to understand the concept of mode for following data:
120 , 110 , 130 , 110 , 120 , 140 , 120 , 130 , 140, 120 ?
The solution of these data is defined as:
In this example we observe the value 120 has the maximum frequency therefore mode or modal value is 120.
Example 2) Find the mode for following data-
15 , 20 , 25 , 18 , 14 , 15, 25 , 15 , 18 ,16 ,20 , 25 , 20 , 25 , 18?
Values ( x ): 14 15 16 18 20 25
Then the mode for a given set of data is 25 because it has the maximum frequency.
