Pearson's r Correlation

[caryleedavisvideo]

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.

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

[cherylmartin]

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.

[miriamkk]

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

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

[ValdirCarvalhoRibeiro]

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 ?

[TimSter]

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

[ForeverCuteSong]

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

[Mr.AIFella]

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.

[krishanmittal]

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

[memeeerz]

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?

[viktorandersson]

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

[TheBoon]

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

[anomalyp]

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