Absolute Measure of Dispersion
The measures of dispersion that are measured and expressed in the units of data themselves are called Absolute Measure of Dispersion. For example – Meters, Dollars, Kg, etc.
Some absolute measures of dispersion are:
Range: It is defined as the difference between the largest and the smallest value in the distribution.
Mean Deviation: It is the arithmetic mean of the difference between the values and their mean.
Standard Deviation: It is the square root of the arithmetic average of the square of the deviations measured from the mean.
Variance: It is defined as the average of the square deviation from the mean of the given data set.
Quartile Deviation: It is defined as half of the difference between the third quartile and the first quartile in a given data set.
Interquartile Range: The difference between upper(Q3 ) and lower(Q1) quartile is called Interterquartile Range. Its formula is given as Q3 – Q1.
