The mean, also known as average, is the sum of all values over the number of values. This is a measure of central tendency: a method of finding a typical or central value of a set of numbers.
The simple mean uses the successive addition method internally to calculate it's result. Errors in floating-point addition are not accounted for, so if precision is required, the standard mean method should be used instead.
This runs in O(n)
, linear time, with respect to the length of the array.
Examples
mean([0, 10]); // => 5
mean([0, 10]); // => 5
