Much of statistics is based upon using data from a random sample that is representative of the population at large. From that sample mean, we can infer things about the greater population mean. We'll explain.

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!

After 2 courses in statistics the difference between the population mean and sample mean was never fully flushed out. I appreciate your clarity on this.
Just wow, I already knew this things but now I know the meaning of all this. Thank you Khan Academy.
You draw beautiful sigmas.
Funny I learnt the exact thing at school today!!!
did you know that i love MATH??!!
thanks for all the help khan i really am thankful for it. THANKS LUV U
i like the way you say statistic
Very helpful thabks !
which t test would u use
Pies
Please add Korean translations
Why is the notation in an alien language..? I just don't understand why
maybe thts y u typed it in
Can't we just put 5 instead of a small n when it comes to the notation?
You can, but the formula just general notation for any case, n might be 8 or 200 in another question, so we just use a variable. But in this case, you're right, n can be subbed for 5
or you can pray for a sign from god
lol
You talk too much
