Mean, Variance, Standard Deviation
The variance is a measure of how spread out those numbers are among each other. The range between the highest and lowest numbers would indicate variation. Generally, the smaller the range the lower is the calculated variance; the larger the range the higher will be the calculated variance.
The variance is calculated as the average squared difference between each number and the mean. For example, for the numbers 4, 5, and 6 :-
1) To calculate the Mean, Variance and the Standard Deviation input the numbers in the text box separating each number with ONE (1) SPACE ONLY.
