follow the following steps to calculate the standard deviation :
1. find the mean of the observations
2. subtract the mean from each observations
3. square the result gotten from the answers gotten in the previous step
4. Add each of the squares gotten above and divide by the number of observations
5. find the square root of the answer gotten in the above stage
