How do you find standard deviation?

To calculate the standard deviation of those numbers:

1. Work out the Mean (the simple average of the numbers)
2. Then for each number: subtract the Mean and square the result.
3. Then work out the mean of those squared differences.
4. Take the square root of that and we are done!

What is standard deviation formula with example?

Standard deviation formula example: The mean is 16 ÷ 4 = 4 points. Subtracting the mean from each number, you get (1 – 4) = –3, (3 – 4) = –1, (5 – 4) = +1, and (7 – 4) = +3. Squaring each of these results, you get 9, 1, 1, and 9. … The standard deviation for these four quiz scores is 2.58 points.
