Mean is also known as the average value for the given set of data in the mathematical term it is also known as the arithmetic mean. If A is a matrix whose columns are random variables and whose rows are observations, then S is a row vector containing the standard deviations corresponding to each column.. Enter your values. Also, the coefficient of variance calculator allows you to calculate coefficient of variation (CV, RSD) of continuous data or binomial (rate, proportion) data. Where the mean is bigger than the median, the distribution is positively skewed. The difference between the largest and smallest data is the range. In statistics, standard deviation refers to an indicator that shows by how much the individual members of a data set/group vary from the mean value for the data set.It can be calculated both for a population case in which it is referred to as population standard deviation and for a sample case in which is called sample standard deviation.
