Pearson's r Correlation 

Without a doubt the most clear and understanble explanation of Pearson's I've ever seen. Thank you so much.

Great video. It might be useful to say that there is no linear relationship when r=0, rather than there is no relationship at all. Non-linear relationships can still exist between two variables when pearsons r=0.

brilliant brilliant video. this video in 4 minutes taught me what my lecturers couldnt teach in a whole semester.

To the person that made this, I am very thankful as you saved my ass and the ass of my team in how to explain the Pearson r correlation, once again thank you

Wrote down the wrong formula in class, was figuring out what was wrong.... Thanks a ton ~!!!!!!! for the simple explanation

Would probably have failed my exam without these videos haha! Thank you so much! :)

I really love the simplify of this video!! This was so very clear. It's such easy math once we know how to read the equation.

Thank you so much for providing such knowledge for free.

Isn't it easier to simply convert the datas into Z values, multiply each pair together, add them together and divide by the total number of datas minus 1 ?

Beautiful, thank you!!

Thank you very much! I was running out of statistical tests to do but forgot about the most simple!

Within 4 minutes, you have explained the topics that took my day searching here and there looking for a good explanation. Thanks a lot sir. Like+ Sub to your video and channel.

A perfect ending to a math video.

Finally a math video with a white dude who speaks clearly. Much love.

great explaining. helped me so much more than my book!

Thank you so much for the explanation

thanks for the simple understandable explanation

Very clear explanation, thank you.

GODDAMN! SO FUCKING CLEAR! THANK YOU

This video has been amazingly useful. Thanks

hi, your explanation is very good but have one doubt. How did you changed the value of SUM yi2 from 1488964... to 212890000?

Best yet❤️👍🏾

Thanks this really helped me alot to understand Pearsons r correlation (y)

Thanks for this!

Thank-you, your are much better than my stats lecturer; what you did in 4 mins he does worse in 1 hour.

Just great.. thanks so much.

Why is there that little 'i' after 'Sum of all X squared'? What does the 'i' mean?

fantastic video :)

thank you!!

Anyone else in here didn't get it the first time n is still lost?

Can you explain the meaning of R? Why the formula is like it is?

i was asked at school to find what statistical test to use when the research is abour relationship between stress level and learning preference of students.what statistical test should i use?

Dude u are the owner of an epic voice! xD

Sweet Jesus!

I keep on getting figures at 0, im using only 3 pairs of data should I use more?

why is it that the upper limit is 1 and lower limit is -1?

he does a very good job at explaining this but his voice is extremely annoying
