Detailed explanation-1: -The reason is true The Quartile Deviation can be defined mathematically as half of the difference between the upper and lower quartile. The quartile deviation = 2/3 of the Standard Deviation.
Detailed explanation-2: -So, to calculate quartile deviation, you need first to find out Q1, then the second step is to find Q3 and then make a difference between both, and the final step is to divide by 2. It is one of the best methods of dispersion for open-ended data.
Detailed explanation-3: -The quartiles are defined as the 25th percentile and the 75th percentile. Hence, for the normal distribution, these define a narrower interval than does one standard deviation on each side of the mean.
Detailed explanation-4: -The quartile measures the spread of values above and below the mean by dividing the distribution into four groups.
