Variance Calculator Instructions. This calculator computes the variance from a data set: To calculate the variance from a set of values, specify whether the data is for an entire population or from a sample. Enter the observed values in the box above. Values must be numeric and may be separated by commas, spaces or new-line. Variance is a measure of the deviation of the random variable from the Expected value in probability theory. The Variance of a random variable X is denoted Var(X). The Variance of a random variable X is denoted Var(X). You can compute the variance using Excel by using the =VAR() function, but the advantage of ours is that it is a variance calculator with steps. Also, notice that if you take the square root of the variance, what you get is the sample standard deviation.

Probability and relative frequency are the same; thus, statistical data and Why not take an online class in Statistics? Mean and Variance of a Discrete Distribution. We have already studied how to calculate the mean and variance ( and  The exponential distribution calculator finds out the probability of a certain amount mean - it is equal to μ = 1/a; median - it is equal to m = ln(2)/a; variance - it is  A very comprehensive collection of online calculators and other interactive probabilities, and this page will calculate Expected Value, Variance, Standard  In this column, you will multiply each x value by its probability. The table helps you calculate the expected value or long-term average.
