Analysis of fluctuations in Credit-Deposit Ratio of Indian States: From Pre-Globalization to Post-Financial Crisis Phase
To measure degree of variability in the data set, we measure degree of dispersion in statistics. Standard deviation is the widely accepted measure of dispersion. It is the square root of the mean squared deviations from mean. The square of standard deviation is known as variance and the ratio of standard deviation to the mean or median of the values is known as coefficient of variation. Usually, we prefer the set of observation which has lower degrees of variability to ensure the power of test and efficient statistical results.
