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]

Same

[@kwadwosoadwa7080]

Kwasia then don't watch 🙄

[@Shaihan]

[@ace4deen182]

life save that help me do my homework

[@UnderEveryBookAndCranny]

Thank you soooo much for this video. It really made things so much more simpler! God Bless you!! 👏🏿👏🏿👏🏿

[@81232611]

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

[@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

[@amiiramo4434]

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

[@laboose6598]

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

[@reetkahlon2560]

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

[@danielirambona]

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

[@kendallcordes5123]

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

[@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.

[@dutchvanderlinde8724]

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

[@tomjackson1874]

This helped me out so much, thanks

[@cosmicbeau8770]

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

[@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😅)

[@imaanabid4929]

Thanks for uploading this helped a lot.

[@hello-dv1hw]

Thank you sooo much at helping my lessons!

[@natashasthilaire1950]

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

[@thies2us]

thank you. You spoke loudly (not yell but, some videos out here, you cant even here what they are saying) and very clearly. well done!

[@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!!

Thanks u made my freaking day

[@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

[@francisgeorge9203]

Thank , this is very helpful👍🏾

thanks so much:)
one thing is that is the range just the maximum of values and the minimum of values subtracted?
