How to Calculate and Interpret a Correlation (Pearson's r)

This video covers how to calculate the correlation coefficient (Pearson’s r) by hand and how to interpret the results. Here we use the 'definitional formula' for calculating the correlation, as it is the easier of the two methods. It also makes more sense intuitively than the computational approach to calculating the correlation coefficient.

Love the constant reassurance: "it seems complicated but it's not that bad, let me walk you through it" Yes please walk me through it.

[@marie-fe5qh]

Thank you for presenting a simplified explanation of correlation. This helps a lot in my research. Keep it up!

[@aliabrishami706]

Finally I got one of the hardest thing in stats! Thanks a lot!

[@tropapips320]

Thanks to you. You made the hard thing easy and very interesting!

[@zaoher2556]

Thanks for the Calculations of the Correlation (Pearson's) that was awesome. I am really excited, it's very hard to understand when I see it in the first time. But when I got into it. That's easy to understand. Thank you so much.

[@waleedsaleem606]

Thank you so much!! You made it so simple

[@SnezhannaPankratova]

Thanks! I like how you go step by step!

[@mytong5338]

Thank you for a great video. Very easy to follow.

[@samuelnkansah9723]

This was very insightful

[@tetlleyplus]

Awesome! great lecture!

[@theodoresweger4948]

Thank you so much, I cannot say why but I've had a hard time with this and some of the explanations went over my head, this was very simple and easy to understand the process. I have done a little tottering in math and I'm sure you cannot please everyone. This process really gets you on the ground and if you feel you need to go deeper you will be ready to handle it. Thank you again.

[@jeanchaaly3307]

Many thanks for this video, is it possible explain how to find the spread between pairs ?

[@gabepierce8427]

this was so helpful thank you very much

[@theboys8947]

Thank you so much! This explanation is much easier to understand! Helped save my grade hahah

[@bashirissack8653]

Thanks for ur explanation on correlation and confections it add a lot of value to my learning

[@rikkihatfield7766]

Simple and easy to understand.

[@peaceloveawsomeness]

THANK YOU SO MUCH!!! this is what exactly i needed. I followed along with a problem from my textbook and i got it right thank you!!!!

[@raymondbenny8322]

Thank you so much. It helps me to get down my assignment.

[@megtmatthews]

Very helpful. Thanks!

[@louisebell2918]

Such a helpful video. Thank you.

[@anthonycarbonaro7890]

Why not show the correlation equation at the beginning?

[@KM-lf5be]

wonderful.... a very clear explanation.

[@bazlfatima843]

Don't you have to divide the standard deviation by n-1 before square rooting it, so it would be SSx/n-1 ie, 10/4. Also for the final formula the denoinator includes n, making it n*SSx*SSy

[@almezamorra1021]

He just simplified everything. Since if you divide SSx by n-1, that would basically mean that you would have to use Covariance instead of Cross Sum. What he did is basically cancelling n-1 from the numerator and the denominator.

[@DimphoTsaModimo]

Thank you soooo much! Much appreciated!!

[@chikwandamulenga2137]

this is beautifully done

[@diamant6022]

Thank you so much. It helped me a lot

[@ZuleikhaPAli]

Thanks you. This is very useful

[@xiongly435]

Wow- you explained it all in 1 module o..........o and made it so easy

[@yessaminalvarez2733]

THANK YOU!!!!

[@strangerdawnvods]

The thing is, how do you find N? On the table there is (3,5), but I don't see the reason why the 5 of the third term, is N. It doesn't look to be a mean to anything either. Or, what is N really?

[@rashikanda9240]

How do I calculate average correlation in excel (I have monthly performance data for 10 hedge funds)?

[@mamtabkbk6292]

Thank you sir

[@sarinaonthego14]

THANK YOU SO MUCH!

[@iam-drake]

so i added up the varience that's the the deviated numbers and tried squaring them but they'er not giving me the same X value, i've made sure of it to know where the error is from but i'm obviouslly correct because i've cross checked more than 7 times now.

[@Steven-ey5xt]

theres no interpreting in this video

[@joeyswoles]

That was a great explanation thank you

[@evodiakhalisee1584]

crystal clear

[@romanvasiura6705]

Thank you!

[@wreetchyl24]

What happen if the mean of x and y has decimal point? Plus the sum of all the mean of x and y is not equal to zero , 🥲🥲🥲

[@ochukasamwel3429]

Thanks so much

[@Benchmark243]

Thank you

[@simontannor6509]

THANKS

[@joriandekorte]

If I put this in SPSS, it gives -1. How's that possible?

[@colpireduro9255]

How to find the x and y sir?

[@nansubugaresty9450]

You made it for me

[@GardenStateSM]

what happens when you have N=200

[@user-je4xw6tx3k]

when i move my mouse, i found it doesn't work.

[@johnmandrake8829]

awesome

[@prasadkj7667]

Very nice explanation, we can learn very easily in this way. Thank you.

[@user-vx5vp7ig4t]

nice

[@kassysaucedi6184]

this is impossible. I keot getting incorrect answers.

[@zofhiasmith5367]

8:54 how did u get -9/10 =‐9

[@user-tm5gx9iu6q]

-9 / 10 = it's negative - 0.9 not 0.9

[@billyjoe7816]

What type of witchcraft is this

[@vadimkorontsevich1066]

good explanation thnx.
but are you recording this video being drunk? you are talking so drunk -styled, that it seems to me, that the next moment you will fall asleep
