Sal, i begin studying for my MBA spring '13 at The George Washington U. My first class is a statistics based managerial class. I have no doubt that these videos are providing me a compararative advantage over my classmates
thank you for posting this video, my course's slides just give us that formula at the end without fully explaining how they came about. At least by breaking it down I understand the basic steps of the formula
You'r an excellant tutor btw.. There was a day, in the 70's when if you wanted to calculate any of this stuff then you had to write the entire calculation as a function in code. Often times you'd run out of memory by the time you tried to apply any of it, but these days even php has a built in stats_varience() function. One of the main reasons my math went to hell was the rise in ready made functions in computer programming languages. It removes you from the mechanics of the problem too much.
How is this sample variance. Isnt this population variance? The formula for sample variance involves dividing by n-1. I even double check on calculator and squared my population variance
Hi Sal, thank you so much about everything you have done, it is very helpful. May i ask you, what program you use to record lessons? it is very neat. Wish you all the best always. (best teacher ever)
This courses explain statistics better than a college course

The tv was drawn so beautifully
How do you do everything? I mean... You are literally an ocean of knowledge, Super amazing. Hats off to you..
@0:56 Sal makes a perfectly round dotted line. I couldn't get over how well it came out.

Thanks, Sal. You are helping me avert terminal boredom, and meanwhile, I'm learning how to avert it's recurrence myself!
Clear, crisp and concise.
thanks i got it now much appreciated ❤🎉🎉

Wonderfully clear explanation. Thank you
10min of your video is better then 3h of my lecture
Thank you.
awesome explanation
Nice Tv!
whay are there 2 videos for the same topic !!!
Good eggs khan
Why it is better to divide a number less than total? Ans mathematical reason for that????
why can't i view any Khan video's from the last week including this one? just black video, no loading etc.
Stats exam in January anyone? :(
Yes lol even tho I’m late
2nd
Isn't this Inferential statistics? The title should be changed.
