Calculating r and r2

[@metalqueen237]

I’m an art student, currently taking a statistics class bc its required. Math has always been my biggest weak point, to the point that i have genuine anxiety over it. I’m studying for my statistics final now & the way you broke this formula down made it so simple. everything makes sense now. You just saved me hours of studying & frustration. Thank you!

I really want to give you a big hug right now! Thank you! Ive been struggling on this one problem for 3 hours, and finally decided to look up a video and you made it so clear and easy! Thank you so much!

[@annakaxandraescano5233]

So grateful to you. I've been studying for more than an hour now and in less than 15 minutes you made this problem so easy for me to understand. Thank you so much for taking the time to explain this step by step.

[@nicholasniedzielski4707]

your handwriting is on point, thank you for the easy demo

[@sammiebeaalex416]

Thank you for your expertise in math because it was so hard to understand how to do this calculation and you have broken it down flawlessly and I completely understand it now. Many blessings to you. Thanks

wow i literally learned this in 15mins and can't learn any thing in 2hr 30mins of my professor's summer class... thanks a lot.

[@EEMalinoski]

You're welcome!

[@waqikhan2100]

Yahhhh v easy

[@manjeetgroverlndnmj]

Coz here , r formula is not explained how it comes in picture that's y it's some what easy 😂.

[@tessellate1962]

It is a skill to make it seem so simple in 15 minutes. Thank you very much. Cramming for my AP Stats exam 9 years later!

[@atlas_the.wolf._4285]

Thank you for explaining easily how to work this formula!

[@incredibledjam5107]

Thank you very much Erika!! Hopefully you will make videos for every math concepts used in datascience as well.

[@jonathanpalmer1473]

2 minutes of this video answered more than 1 hour of my trying to figure it out from reading my textbook and looking at examples.

[@MegaSharkboy10]

Thank you so much (: helped alot

[@ridonngandu8290]

Thanks this is gold 🏅😊

[@fishtacosyt8835]

This was very helpful. Thank you!

[@samantha-dy2ow]

thank you, this helped a lot!

[@RaulPelcastreRealEstate]

Hi Erika, great video, you're gifted :-) can you post the entries of your TI-83 Plus? I can't see the final entries to arrive at the R. I have (7*18458*678-166)/(√ (7*67892-678^2)*√(7*6768-166^2) but I get a different figure than 0.94856

[@FSWML]

Hi! Correct me if I'm wrong, I'm just a student who's learning and I would like to understand if we would arrive at the same answer if we were to use the formula for 'r' as CovAB/S.D of A * S.D of B

[@tanishqvyas8387]

Really nice explanation. thanks

[@thejungleelf3240]

Thank you so so much!! needed this :_(

[@sarabjeet1241]

thank u soo much
its really worth it . :) :)

it was perfect
I learned it

[@killzr6599]

well expained

[@mypenguin9692]

Really amazing 🙃

[@MichelleyB.]

is each dot on the scatterplot an x and y, you used to add everything on the first long line?

[@kewlaldo10]

How do you do this for a non linear trend line?

[@JonathanMalambo-od9jy]

What does the r and r^2 represent is it th sam as correlation

[@thelasagneman6184]

what if you get an r value over 1?

[@volcano6921]

u will get mistake cuz cant exeeds 1 ever

[@henrychn]

Awesome!! I got 100% thanks a lot

[@Dinahmcc]

Wow, color-coded pens, even!

[@user-wv7hn6jb2h]

How to get R2 without intercept?

[@jairosalazar1011]

Great! Thank you!

[@rashidahasan7726]

what is y here ? is it dependent variable ?

[@AsfandYar]

thank you

[@crimsynheartticker3732]

thank you thank you thank youuu

[@foxtrqt8915]

Thank fuck for this video omfg

[@sylviastevoo2391]

Thanks alot

[@michellespiegel4646]

Watching all the way to the end and she starts using the calculator and I couldn’t see what she typed in. The bummer is, r= is what I wanted to see. Ugh!

[@atoafful4965]

I don't know who you are or where you are, but i will find you, and I'll give you THUMBS UP!

[@EEMalinoski]

LOL! I recorded these for my Intro to Stats students a couple years ago when I flipped my classroom.

[@tafadzwamachina6143]

uridhara well done i love you
