How to calculate interquartile range IQR | Data and statistics | 6th grade | Khan Academy

Learn how to calculate the interquartile range, which is a measure of the spread of data in a data set.

Grade 6th on Khan Academy: By the 6th grade, you're becoming a sophisticated mathemagician. You'll be able to add, subtract, multiply, and divide any non-negative numbers (including decimals and fractions) that any grumpy ogre throws at you. Mind-blowing ideas like exponents (you saw these briefly in the 5th grade), ratios, percents, negative numbers, and variable expressions will start being in your comfort zone. Most importantly, the algebraic side of mathematics is a whole new kind of fun! And if that is not enough, we are going to continue with our understanding of ideas like the coordinate plane (from 5th grade) and area while beginning to derive meaning from data! (Content was selected for this grade level based on a typical curriculum in the United States.)

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.

When I heard my teacher explain this, I was like 'Huh?'. Now, I get it. In my opinion, the easiest way to explain math is to make it simple.

"This is strangely fun." Love it hahah :)

[jpakash]

Studying this in post graduation and seeing 6th grade in the title :)

It’s currently 3am and I have a test tomorrow, I couldn’t sleep so I decided to review this, and oh I am so glad this video exists 😂 thank u so much btw.

[PlayboiFari]

the amount of times his videos saved my test grades

[cottontabby]

thank you so much, it helped me so much! this is the first time im learning IQR, and i immediatly understood after the first example.

[savannahhamama]

Great math videos, I subscribed. My teachers aren’t always good at explaining this really helps. Kudos to you guys! Love the website as well.

[nou]

Could you next time also say what does it do in practical use like why are we calculating IQR

[themagicpotato]

he sounds like he should be reading some reddit comments instead of teaching math, his voice just fits it... kinda like damien

[AnthonymarioOrozco]

Thanks I couldnt have done my math homework if it weren’t for u

[C.M.M]

Tnx u helped me out a lot I think that now I will pass my test

[wonder_doesstreams]

This video may be old but it helped ALOT

[kingng]

The examples you show and the way you spoke actually is so much easier to understand! Thank you saviour!

[CrazyCat]

Thank you for making math understandable for someone with a learning disability. Listened to this lecture topic in class and felt so confused when my instructor explained it.

*Middle of the first half of data before the median subtracted from the middle of the second half of data after the median = interquartile range. (When there's an odd amount of numbers.)*

*Median of first half of numbers subtracted from median of second half of numbers = interquartile range (when there is an even amount of numbers.)*

Thank you for this :)

[silmarilion]

God his voice is so soothing and seductive. Almost makes me like math. Almost.

[mia-hgpn]

Thx!! i have test tomorrow wish me good luck!!!

[magmagold]

when my teacher first taught us this I was confused but until I saw your video and it just makes more sense to me!

[awesomeferret]

Let's be honest though, if you ever want a legitimate example of something in math that 99+ percent of people will never need to know, this is a pretty good one. It's actually a challenge to think of scenarios in the real world where this would be used.

[kelly_rmt]

Honestly this made my math easier. Thanks.
