Explanation:
Detailed explanation-1: -It is defined as the square root of the variance. If the dispersion is small, then the values in the distribution is close to the median.
Detailed explanation-2: -If the dispersion is small, the standard deviation is less. It is an absolute measure of dispersion and is the square root of variance in the data. If the data is having small dispersion, then its standard deviation is also less and vice-versa.
Detailed explanation-3: -A small value of dispersion means low variation between observations and average. It means that the average is a good representative of observation and very reliable. A higher value of dispersion means greater deviation among the observations.
