Online sampling statistics calculators to easily calculate mean, standard deviation and variance of sample and population. Sampling in statistics is the selection of a subset of individuals within a statistical population to estimate characteristics of the whole population. Mean is the average of all the data in a set divided by the total number of data in a set. Variance is the average squared deviation of each number from its mean. The standard deviation is the square root of variance.
