In one column there are some alphabetic codes which we assigned to the people and in the next column, we have the age of those sets of people. Now we will look into some other examples with different datasets. Step 4: We will calculate the Standard deviation, by dividing summation with the number of observations minus 1 and we will square root the result. Step 2: For each observation, subtract the mean, we will put it in the tabular form for the convenience,Дouble the value of the column second (Observation вЂ“ Mean)^2. Step 1: Calculate the mean of all the observations, LetвЂ™s take an example and follow these steps. Examples with Steps of Standard Deviation You will get the standard deviation as a result after completing 4 steps. Step 4:В Lastly, divide the summation with the number of observations minus 1.Step 3:В We got some values after deducting mean from the observation, do the summation of all of them.Step 2:В Then for each observation, subtract the mean and double the value of it (Square it).Step 1:В Calculate the mean of all the observations.Steps to calculate Standard deviation are: Hadoop, Data Science, Statistics & others
