Probability and statistics on Khan Academy: We dare you to go through a day in which you never consider or use probability. Did you check the weather forecast? Busted! Did you decide to go through the drive through lane vs walk in? Busted again! We are constantly creating hypotheses, making predictions, testing, and analyzing. Our lives are full of probabilities! Statistics is related to probability because much of the data we use when determining probable outcomes comes from our understanding of statistics. In these tutorials, we will cover a range of topics, some which include: independent events, dependent probability, combinatorics, hypothesis testing, descriptive statistics, random variables, probability distributions, regression, and inferential statistics. So buckle up and hop on for a wild ride. We bet you’re going to be challenged AND love it!
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We’ve also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

what is the difference between sd of sampling distribution and sample sd (i.e s)?
sample mean – mean of sample distribution. How do you find the mean of sample distribution?
Excellent!
you can chronologize (numbering) the videos so that we can understand in which sequence we have to follow your videos to understand Statistics.
Getting to learn statistics for my own good and trying to have knowledge on inferential statistics. Trying to learn that subject since am an aspiring economist
This video could be half as long if you didn't repeat himself so many times

I don't understand is he saying n is small or s/n is small or s?
I like this guy, i like this guy, his presentations are excellent, excellent. i do wish that he could break the habit, break the habit, of such FREQUENT repetition — surely he is unaware of how distracting this is, It becomes, becomes annoying…..
What to do if you need t test but sample is 209
2:34 "divided by population mean" i think u meant "population standard deviation"
Gonzalez Kevin Gonzalez Jennifer Garcia Christopher
shouldn't we use t-test when population variance is unknown, no matter the sample size?
The constant repeating of last 2-3 words every 5 seconds makes this very hard to follow. Also, at 2:29, what is the "mean of our sampling distribution of the sample mean"?? I have not heard it expressed like that before. I do appreciate most of the Khan Academy videos, but this one missed the mark a little.
