Mode
In statistics, the mode is the value that appears most often in a given list of numbers.
Inspection Method
MODE (Individual Series): Inspection
Method
Marks Marks
2 2
Two times
5 2
7 3 One time
Arrange the Data in Ascending Order
5 5
6 5 Three times
2 5 By Inspection of the Data it is clear
that the value ‘7’ occurs most
5 6 number of times in the series i.e. 4
One time
7 7 times
3 7
Hence Mode = 7
7 7 Four times
7 7
MODE (Discrete Series): Inspection
(Frequency Array) Method
Wages f
100 2
200 1 The value ‘300’ has
highest frequency i.e
300 4 4
400 2
Hence Mode = 300
500 1
Grouping Method
MODE (Frequency Distribution) : Grouping Method
(Class Interval Series) (Grouping and Analysis table)
Frequencies are grouped in twos and threes
Mark the highest value in all columns
Mark the values corresponding to highest value in all columns
Modal class = 200 – 300
Wages (I) f (II) (III) (IV) (V) (VI) Total
0 – 100 2 1
3
100 – 200 1 7 3
5
200 – 300 4 7 6
300 – 400 2 6 7 3
