MODE (Discrete Series): Inspection Method
(Frequency Array)

Wages f The value ‘300’ has
highest frequency i.e., 4
100 2

200 1
Hence Mode = 300
300 4
400 2

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

Relation between Mean, Median and Mode:
Mode = 3 Median – 2 Mean
