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!

Can someone help me with this question cause i don’t think I’m doing it correctly ( 100 mice in a lab were weighed their mean weight was 53,5g and the inter-quartile range was 7 g. Estimate roughly how many of the mice weighed more than 52 g, explaining your reasoning clearly) I mean you don’t have to help if you don’t want to🥺

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.

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.

Can anyone help with calculating SD from IQR?

What if the two middle numbers for the median

AREN'Tthe same?hi, i love your vids

I get the math but what does the iqr actually tell?

Sid

This waa fun

I like that you are helping out with my school work! 🙂

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?

Thank you so much! My teacher couldn’t explain this well at all and I didn’t get it but now I do.

I really needed the help thx so much!!

It says right there 6th grade but why is my teacher making me do this when im in 5th grade ;-;

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

i get it but im still kind of confused as to why we still need to know (in the second question) that the average of the two middle numbers is 10. its not technically needed for the IQR so is it just an extra step?

nice video my dud

This is actually trash

This helped alot, Thank you so much!

honestly still don't understand this?

Honestly this made my math easier. Thanks.

that kid with fifteen animal crackers is the same kid that has 3 cans of coke instead of 1

he sounds like good times with scar 😂

who els is in mr blacks class 6th grade

If i have an odd set like 5 numbers do i just add and then subtract each number on every side

School is so

thanks so muc

I wouldn’t be alive if it wasn’t for this guy

Very helpful thx!!!!!!!!!!!!!!!

😉 ;D

This helped me so much

I forgot what IQR meant for a second, thank you so much

I’m still confused

So IQR = the middle 50% range of a data set?

👌👌👌👌

My name was in the video!

so this is for 6th graders 😑

thank you this helped a lot

I hate how he did an odd set of numbers, it’ll be more efficient if it wasn’t even so we can see how he got the median then

So well explained, thank you!

Are you Canadian? The way you pronounce things seems Canadian

Thanks dude!

what if you have 10 numbers instead of 9?

This is helpful when u forget how to do your homework

Great video👍
