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.

[@josephvalle3581]

I have a project too, AND I HATED

[@josephvalle3581]

Because my Partner don't help me

[@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.

[@elariarich4002]

Thank you so much :) brilliantly explained and you sound like Tom Hanks ! haha :D x

[@_starful7602]

Thank you, your videos are greatly appreciated. ^^

[@fx3ozzie254]

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

[@32antshotit]

This definitely helped me. I haven’t made one of these in a very long time and I have regents next month. So thank you

[@samarasatya7474]

Thx Sal, my man! This helped me alot to understand Box and Whisker Plots for my finals tomm

[@onlyonemitch5049]

I cant believe i used to fail these simple things!

[@vidhyadharp]

Thanks for brining in clarity for me.

[@dollchromed]

im so thankful for KA, its helped me since i started school, and im so appreciative for the videos it gives to help me have a good education.

[@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.

[@user-eb1mj1zv6i]

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

[@b4rkley526]

thank you this helped

[@professional_silent_trumpe1540]

[@Monkaii]

Best explanation out there....Much Appreciated!

[@ShurikenTY]

this brought me to the old youtube layout, siick

[@all_paca]

I didn't know a box plot was also called a whisker plot! Neat!

[@alltimegaming301]

Good one mate love from India:)

khan sahab you are the best!

[@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.

[@mcguirefamily4529]

This video was so helpful thank you

never disappointing ! thank you .

[@ratulroychoudhury6008]

it helps me a lot,thank you

[@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.

[@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!!!!

[@aidenmeagher7012]

A good video

[@psychedelicrelic8805]

Coming in clutch for my stats final tomorrow

[@nina-mv1bf]

This helped soooooooooooooooo much!!!!!!!! thxxxx

I am home schooled and went here myself to learn more because I am a nerd.

[@miarenee1]

Omg thank you so much for your help!

[@KeepItShuffled]

I was Never taught box plots Strangly enough and I'm in tenth grade.

Welcome to hell

[@saronworkeneh6731]

👌👍👍👍👍👍👍👍

[@Crackedatsnipers]

I'm still wondering how I'm learning more on RUclips 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
