Calculate the standard deviation of the following set of numbers. Use the formula for the standard deviation (s) shown, where x represents the values, n is the number of values, and is the summation symbol, which indicates that you should add the values. S = x = 1 n (n 1) (n x - ( x)) Do not round your answers. x = = values: x = 12, x2 = 22, x3 = 17 Step 1. Calculate the square of each data value. O Macmillan Learning x = Step 2. Determine n times the sum of squares of the three values. n[x = Step 3. Calculate the sum of the three values. 2 x= Step 4. Calculate the square of the sum of the three values. O Macmillan Learning Step 4. Calculate the square of the sum of the three values. ( x) = Step 5. Calculate the variance. 1 n(n-1) (n x - (Ex)) = 5 Step 6. Calculate the standard deviation. 1 n (n 1) (n x (Ex) ) =
