Learning Outcomes:-
Through this module, you will gain understanding on:-
1. Mode
Calculation of mode in individual series -
1) by inspection
2) By converting individual series into discrete frequency series
Calculation of mode in Discrete series OR Frequency Array -
1) Inspection method
MODE
Another important measure of Central tendency of statistical series
Value which occurs most frequently in the series (Highest frequency) = Modal Value
● Mode is the value of the variable which occurs most frequently in a distribution
Derived from french word ‘la mode”, meaning a thing in vogue or fashion
Represented by letter Z
Calculation of mode in individual series -
There are two ways -
1) by inspection
Simply identify the value that occurs most frequently in the series
When to use the inspection method?
● In such series where different items show different frequencies
● Number of items in a series is not very large
2) By converting
individual series into discrete frequency series
Arrange data in ascending order
Convert the series
Calculation of mode in Discrete series OR Frequency
Array -
1) Inspection method
● Value that has the highest frequency in the series
● Used when series are regular and homogenous

A glance at the series reveals that 140 has the highest frequency of 10
Hence, Mode (Z) = 140
2) Grouping method (mode in Discrete series OR Frequency Array)
If more than one value has highest frequency in the series
Method involves construction of -
a) Grouping table
b) Analysis table
