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!

Wouldn't 1 SD get you .34?
THANK YOU VERY MUCH 🙂
I found this very useful.
o— = 1.1 kgs right? and not 1.1 gms
*Tears* thank you!!
This is what I have been looking for! Finally a few videos outlining how to complete actual questions. Theory is great to know, but it really wasn't helping me actually answer any of my questions in assessments.
Okay, I understand how you would get this. But I have a problem with the same concept but I cant seem to get it!
1. The pulse rates of healthy adults are normally distributed with mean 72
and standard deviation of 5.
a) What percentage of healthy adults have a pule rate over 80? (Hint:
You may want to use Excel here.)
at the 95% mark it's 82. do I still use the same method? Is there more calculations?
Thanks for sharing!
Thanks man! thanks for sharing!!
awesome.. u just made it so much simpler
This is amazing! Great work!
Each of the legs of the 68% region are Left=34% & Right=34%, not 32%.
