Β
Range
Range = Maximum value β Minimum Value
Β
For data
5, 10, 15, 18, 21, 24, 24, 13, 2, 9, 9, 18, 18, 32, 28, 3, 14, 25, 3, 27
Β
Maximum value = 32
Minimum value = 2
Β
Thus,
Range = 32 β 2 = 30
Β
Mean of Raw, Discrete and Grouped Data
Median of Raw, Discrete and Grouped Data
We can also find median using Ogive curve
We draw less than and more than ogive,
Β and their intersection is the median
Mode of Raw, Discrete and Grouped Data
Mean deviation about Mean and Median
Β
Variance and Standard Deviation
Β
Coefficient of Variation
