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. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps.

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.

[@lemon-oi5kl]

J R Animation Studios cool my teacher doesn’t teach this. She teaches easy stuff.

Totally agree, to be honest some teachers tend to try to explain things complicated and the easy things seems hard

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.

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.

[@kingng7383]

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

[@CrazyCat596]

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.

[@epsteinsuperforce]

ive never been able to wrap my head around this, but this video actually helps a ton, thanks

[@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.

[@AnthonymarioOrozco]

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

[@curlylocs6073]

*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.

What if the two middle numbers were different on the second example. Like they were both 10 but what if it was 9 and 10 how would you average them out?

[@tannerz21gaming65]

If the median of all the numbers is the same, do you have to include those numbers back into the first and second sets of numbers?

u use it whenever u get tested on it in math class

what we would say to median .... can we say it quartile Q2 as well .... coz lower & upper quartiles are Q1 & Q3 respectively ... isn't it ? if I'm not wrong.

[@soniagupta5111]

नमस्ते । Sir, I I had one doubt. What is the use of finding the median of the numbers which we wrote in an increasing order in the beginning of the solution, because later on, we didn't use that number

well what if there is two numbers next to the median so the middle number wouldnt be there since its only two

How do you find the mid hinge... Mid quartile? Q1 + Q3 divided by 2???

Are you talking about the median?

[@asharhabib1060]

You do that by Q2= number of scores + 1 divided by 2
