yanasidlinskiy · Answer

First you find the mean of the differences
Add the squared diffferences
Divide by the total of the numbers in the data
Take the square root of the mean of the differences to get your SD

https://www.mathsisfun.com/data/standard-deviation-formulas.html Follow the steps. And I notice, fewer and fewer people seem to want to help you. I suspect it is because you never seem to participate in the problem-solving process. Show some of your work, interact, show that you are interested in learning, not just having problems solved.
