Answer:

  1. Subtract
  2. Square
  3. Sum(add)
  4. Divide
  5. Square Root
  6. Round

Explanation:

The standard deviation of a data set is computed using the formula:


\sigma = \sqrt{(\sum_(i=1)^(n)(x_i - \mu)^(2))/(n)}

where
\sigma is the standard deviation,
x_i are the individual data values,
\mu is the mean and
n is the number of observations

So we first subtract the mean from each data value

then we square the result

then we sum(add) up all these values

then divide by n

and finally find the square root

The round operation will occur after all the above calculations
