It is a measure of dispersion based on the lower and upper quartile. Quartile deviation is obtained from interquartile range on dividing by 2, hence also known as semi interquartile range. How to Calculate the Interquartile Range? The procedure to calculate the interquartile range is given as...
Coefficient of Quartile DeviationA relative measure of dispersion based on the quartile deviation is known as the coefficient of quartile deviation. It is characterized asCoefficient of Quartile Deviation =Q3−Q1Q3+Q1Coefficient of Quartile Deviation =Q3−Q1Q3+Q1...
Like the standard deviation, the interquartile range is a measure of dispersion, and it may be preferred in cases where the data is not thought to come from a normal distribution for some reason. For example, if there is not a lot of data, or the data is not continuous, or if the ...
