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
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
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.
