Hey..!! Can You Help Me Out!! The formula of SD for Grouped Data is root over submission of {f(m-X)^2} whole divided by "n"
But He has written divided by (n-1).

[@HotFiya05]

@@surbhi1353 This is late, but since it's a sample, you divide by n-1. Total population you'd divide by N

This man is the best tutor I ever had. I love his voice, l love the tidiness, love the calm way he explains and make problems look so easy to solve. I wish I could meet him in person. I am a teacher preparing for my GK Test to get my permanent teacher certification, I paid a tutor from a University, what a joke that "Doctor Harrington" is. I will never look for anyone different than JG The Organic Chemistry Tutor. If there is anything you need to learn or remember how to solve: Is here just ask the Organic Chemistry Tutor. Thank you so much JG you are truly the BEST!!!!
