Makoto Ritsuka: Thank you so much! This really helped out! (: Dan Curwin: awesomematthew breen: thankskphzorz: 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 YouMolebi Mokobi: thank you very much!Sanjay Shrestha: Thanks70TheProfessor: 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 cutRichardMrWood: 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 mathMidnight 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 youmrsshunnshine: 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 youisaac oliver: yup, would have went into my exam not knowing how todo SD, if it wasnt for USandy 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. |
