Root mean square

In mathematics, the root mean square, also known as the quadratic mean, is a statistical measure of the magnitude of a varying quantity.

It can be calculated for a series of discrete values or for a continuously varying function. Its name comes from its definition as the square root of the mean of the squares of the values.
