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.

Great video! Now I fully understand what is being called 'box-and-whisker plot' and how it works, thanks to KhanAcademy. Thank you so much :x

[@dinosaurgrrr9050]

Me too

[@elementalfilms9083]

i actually understood this concept. i started learning it in advanced math. i was confusing for me in the class. but now Khan has explained it much better

[@gem1900]

well this just made me pass my exam, thanks so much!

[@camerong3926]

Omg thank you so much !!!! I finally know how to do it and it raised my grade to an a thank you so much!!!!

[@fx3ozzie254]

Probs the best explations out there, now that i understand it, its so much easier lol

[@_starful7602]

Thank you, your videos are greatly appreciated. ^^

[@jovannyc7158]

Thanks man! Been stuck for a while. Didnt know it was that simple!

[@kirant9305]

The whiskers are plotted incorrectly. The left whisker should be at Q1-1.5*IQR and the right whisker should be at Q3+1.5*IQR. But, in the video, it says that the left whisker is at the minimum value and the right at the maximum value. If this is the case, then there is no way to identify outliers in the data.

[@zyhfi2756]

Thank you so much I have finals this week and a project about this and I didn’t get it

[@josephvalle3581]

I have a project too, AND I HATED

It is possible to solve the question, what is the median, and what is the number that represents the lower quartile and the upper quartile in the question:34,35,36,38,40,42,42,43,45,50,55,65

[@aatifsalam3782]

Thanks for helping, I understood it much better!

Good one mate love from India:)

[@judsonlevi3386]

that moment when your math teacher forgets how to teach so you have to rely on a three-year-old video two weeks before finals

[@NorthwestFairHousing]

Really helpful!!!!

[@HassaanRaza]

khan sahab you are the best!

[@majorasmrstressrelieving8984]

Helped me remember a lot !!!!!

[@imnotyourrobot9796]

Another way to easily find the median:
Take the number of all the data points. For example, there were 17 data points in the example Sal gave. So n= 17.
Then use this formula:
n+1/2
17+1/2
18/2=
9
Count to the 9th place in the list of numbers in order from smallest to largest.
That is your median.

[@nbdexotic7151]

Dude Thank you so much you explained the video so good and helped with my hw

Thank you so much :))

[@mohdig9]

Why wasnt the Interquartile Range used to determine if there are any outliers? I am taking Intro to Stats and Probability and we need to use Q1-1.5(IQR) and Q3+1.5(IQR) to decide if there are outliers on the plot.

[@adriansese8877]

so what if there's no median in the data in 3:05 do we have to make it up and cancel stuff?

[@grimordwow]

You take the average of the two middle values, like he does later while calculating the edges of the box.

[@Crackedatsnipers]

I'm still wondering how I'm learning more on TH-cam than at school 🏫

[@freshswash9934]

when he drew the box around the 3 medians it really bumped me out that he included 2 and 14 even tho these aren't even in. I might be autistic

[@akeemmahdi3283]

Thanks was VERY confusing before I watched this video
