Very well explained, thank you Joe. For those who use N-1, this still explains the method. N is population and N-1 is sample population. Use the one that fits its purpose.

I totally forgot how to calculate sd which I had studied in school decades ago. Your video came to help. It is just perfect. Thank you so much.

This video was EXTREMELY helpful thanks so much !

This is amazing, however I would have loved to see the multiplication part (bit tedious) for people like me who are not mathematically inclined, however, because I had a little bit of idea about SD I figured it out. Great job, can get even better with the small recommendation. Thank you for this!

It could be noted that the curve is a mathematical formula that never touches the x axis. It was a bit much for me to take in at first, but it has really helped me understand statistics.
