Question
A statistical measure of the variability of a distribution around its mean is referred to as
Solution
The statistical measure of the variability of a distribution around its mean is referred to as the standard deviation.
Here are the steps to calculate it:
-
Find the Mean: Add up all the numbers and then divide by the number of numbers.
-
Subtract the Mean and square the result (the squared difference).
-
Find the mean of those squared differences. (This is called the variance.)
-
Take the square root of the variance to get the standard deviation.
The standard deviation is a measure of how spread out numbers are. Its symbol is σ (the greek letter sigma). The formula is easy: it is the square root of the Variance. So now you ask, "What is the Variance?"
