Flipped 10.2 Frequency Table - Mean Median Mode Range Interquartile Range

Flipped assignment 10.2 for Algebra2/Trigonometry
This lesson shows you how to find the mean, median, mode, range and interquartile range from a frequency table

[@AH-cf6qo]

U just explained 2 weeks of our study in 5 minutes... damn

[@reubenolney1610]

same 😂😂

[@6xmaaaa]

I saw that pic from Pintrest🤡

[@wdzcix]

For median you can just add the frequency together then do the formula n+1/2 using the total as n. Then whatever number you get you count how far into the table it goes for example it’s 5, it would be (for this table) 8 because that’s where the 5th number lies. :)

The marker sounds made me shiver

[@kingpin7648]

TizerGold ya,its a lil cringe ain't it?

[@malekqasim8307]

life save that help me do my homework

[@laboose6598]

Actual gift from god. Thanks so much. I wish our teachers would show us these videos more often.

[@amiiramo4434]

I never knew how to find range but i get it now....! Damn

[@danielirambona]

THANKS!!!, Man that was much more helpful than what my teacher taught me!!!! THANK YOU SO MUCH, THIS HELPED!!

[@81232611]

thx a lot, It's way better than searching for a ton of websites

[@reetkahlon2560]

Thank you so much. You explained the same concept but in a clearer way in contrast to other videos.

[@tomjackson1874]

This helped me out so much, thanks

[@terminatortscc1]

thanks a lot for your help !
solutions for last question-
mode-13
median - 13
mean - 12.38 approx
range - 3
inter-range - 3
i hope they are correct !

[@anasopead5466]

median = 12

[@dutchvanderlinde8724]

I figured out to calculate the mode in the first 20 seconds, thanks to you.

[@imaanabid4929]

Thanks for uploading this helped a lot.

[@natashasthilaire1950]

Thank you so much!! But one quick question, why didn't you use (n+1)/2 to find the median?

[@hello-dv1hw]

Thank you sooo much at helping my lessons!

[@syedahussain1265]

You sir are a life saver!

[@kendallcordes5123]

How did a random guy i found on youtube explain maths better to me than my teacher with a degree

[@makinenivanshita5847]

Omgggggg😍😍😍😍😍cannot believe this. You explained soooooo well, loved your explanation

[@aoifeg313]

Thank you! Struggle with maths a lot. You really helped!

[@cosmicbeau8770]

Omg thank you. I doing a packet with 92 questions and you are a really big help (on question 78)

[@jnelly86]

This was so helpful. Thank you!

[@missnyokaxo967]

THANK YOU SOO MUCH😊. Firstly, I am in the 8 grade and I'm not really good at math so I found this very useful. My teacher isn't good at teaching math so this feels great to find someone who can. For years sometimes I felt like I have been struggling for not getting some terms in math... But because of you I can bump up my grades😁. Please continue to make these videos especially for the eighth graders going to highschool, this gives a thero teaching of how to do a frequency table including things you'll most likely be tested on!!! Btw thank you for leaving the "do it urself" kind of thing at the end, it really helps. (But you forgot to leave the answers😅)

[@Great_WesternTVFan]

excellent explanation. well done!!

[@adnanrahman-arx7870]

thank you so much bro. Best video in youtube abt this topic

[@francoobo7184]

[@Kay-on6ml]

I’m in quarantine right now and can’t attend school, and I had no idea how to do this so thank you so so so much!!

[@francisgeorge9203]

Thank , this is very helpful👍🏾

[@akshat2276]

Merely awesome. very well explained!!

[@JWelton]

Yes, that is a good method to figure out the median. If there are an even number this method will give you the number between them. If there are an odd number, it will give you the one exactly in the middle. Thanks for the suggestion.

[@recognisedbrahh]

Thanks Sir your a legend !!

very helpful thank you

[@84toanpham]

if you have graphing calculator like ti-84, then just plug in those number. ur will be done in less than a minute.
1. STAT-EDIT-ENTER
2. PUT SCORE IN L1 LIST AND FREQUENCY IN L2 LIST.
3. HIT STAT-CALC-(1:1-VAR STAT)-ENTER
4. LIST: L1
5. FREQLIST: L2
NOW HIT CALCULATE
THERE MEAN=
STANDARD DEVIATION=
SCROLL DOWN YOU WILL SEE M= (THIS IS MEDIAN) AND SO ON HERE

[@cnarpehlivanl6046]

Thanks !!

thanxx alot!!!

[@a.kkoirala5418]

UR A LEGEND

[@GamigGuys]

Thanks this helped

[@nityamacharya8374]

Thank you,so finding the mean,mode,range and median is different from finding it with a frquency table to sets???

[@romant6018]

You just done my homework

[@shahg390]

Thanks alot

[@bxncxz8844]

i have exams and this really helped :)

[@NoName-fc5wc]

thanks!

[@sinnamoon]

Thanks

[@legomorriarty7583]

How can the median be 7 in this case?
While finding the median, you have to choose a figure that stands right in the middle of the row: 50% of figures should be lower and the rest 50% of them should be greater than the chosen figure.
So the right answer here is 8.5.
You can also apply the median-formula for even figures. Here: 1\2*(16\2+(16\2+1))=8.5

[@aabidiqbal1944]

great work very well explained i'm 17 and I forgot how to do IQR thanks!
