Did this video help you?

Makoto Ritsuka: Thank you so much! This really helped out! (: ´╗┐

Dan Curwin: awesome´╗┐

matthew breen: thanks

kphzorz: Thanks, this really helped me out.

Dan Munhoz: people complain about there crappy books lol, at least you university students get math professors that can speak English fluently. go to a community college and try passing a math course taught by some Indian dude that sucks at explaining crap...

tridentseven693: I'm taking an online statistics class so I'm teaching myself. This video was awesome! Thank You

Molebi Mokobi: thank you very much!

Sanjay Shrestha: Thanks

70TheProfessor: The shortcut method should give the same answer as the longer method. Be very careful of rounding; that is often a source of differences. This formula is not intended for use with grouped data.

Andrew Bgame: why the heck don't they teach us the shortcut in the first place, this is about 20 times easier than how I learned it. Thanks.

dgcanehdian: Thank you!

wtflez1: Thank you so much!

Austin Clark: how in the hell is this elementary level?

Jackie Smith: I took stats last year, but totally forgot how to find standard deviation! My college professor totally did not explain it well enough, thank you so much!!

Andressguillen: thank you! youtube is starting to become my go-to, free personal tutor!

Jonathan Miller: me tooo yo!!

Lori Aylwin: This was amazing! Thank you! I spent hours doing this the long way and I am behind in my class. Your demonstration will make my life easy. I appreciate you!

swampcat8277: Thank you so much! My teacher flew through this and I was so lost! I love how you did out everything before plugging any numbers into the equation. Extremely helpful!! Thank you so much!

Sandy Mehra: wt the hell is short cut

RichardMrWood: Crazy, I have that book.. i also subscribed to your channel because i thought you were a math teacher. i thinkn your more of a camper... unfortunatly- i wished to learn more aboiut math

Midnight Dreams: I am doing an online statistics class this summer and these formulas are kicking my butt. Thank you for putting this up it was a major help.

mmarandola3: Great! Helped me a lot!

ait yadeen: it makes you wonder ,how someone from 1894 came out with this formula ?

rebecca boles: I like you. You're cool.

Jurgen Thano: Thank you :)

TransientWriting: thank you

mrsshunnshine: Hello, I have been working out both your shortcut version and the long version of standard deviation but my answers do not come out the same. Does it make a difference if I am using your short cut version on finding the standard deviation for grouped data or using midpoints of classes?

Sandy Mehra: hey everyone !!! this answer(0.48) is wrong and the correct answer is (0.57)

Masterballsackwood: I love you

isaac oliver: yup, would have went into my exam not knowing how todo SD, if it wasnt for U

Sandy Mehra: sorry sir, but the right answer is (0.57) and your answer is (0.48)is incorrect....plz explain wt is the matter?

Jon Bobis: Thank you for this amazing video!

NoZain: you rock! thank you.
