But it does not specify the year.Variance and Standard deviation are the two important topics in Statistics. It is the measure of the dispersion of statistical data. Dispersion is the extent to which values in a distribution differ from the average of the distribution. To quantify the extent of the variation, there are certain measures namely: (i) Range (ii) Quartile DeviationStatistics is the application of mathematical concepts to understanding and analysing large collections of data.
