measure of variability meaning in Hindi

The interquartile range ( IQR ) is a measure of variability, based on dividing a data set into quartiles.
It is therefore desirable in analysing the causes of variability to deal with the square of the standard deviation as the measure of variability.
Because the MAD is a simpler measure of variability than the standard deviation, it can be used as pedagogical tool to help motivate the standard deviation.
This assessment involves measures of central tendency or averages, such as the mean and median, and measures of variability or statistical dispersion, such as the standard deviation or variance.
When the median is used as a location parameter in descriptive statistics, there are several choices for a measure of variability : the range, the interquartile range, the mean absolute deviation, and the median absolute deviation.
Some measures that are commonly used to describe a data set are measures of central tendency and measures of variability or mode, while measures of variability include the standard deviation ( or variance ), the minimum and maximum values of the variables, kurtosis and skewness.
