How To... Calculate Pearson's Correlation Coefficient (r) by Hand 

RU-vid is literally my educator these days. School is confusing as hell

WTF. This man has been the only one to explain this to me to where I actually understood how to do it.

I have an exam tomorrow, and your video was soo comprehensive and straight to the point. I thoroughly enjoyed it and gained a lot.

I just want to say, this video saved my life.

I can understand him better than my professor

Finally I found someone who can explain it in simple words and show how to do it step by step. Nothing but appreciation for such a talent.

Great video, this is now the second video I've watched posted by Eugene O'laughlin and I'm amazed by how well he actually teaches you to complete the formula. Thanks a lot!

yup... i'm one of those students who cram the night before the exam!

Thank you Dr. Eugene for taking the time to produce the example and walk us through it, very interesting and clear, thank you.

Thank you so much for your clear instructions. This video is the only one that has made sense to me after looking at several ways of calculating this Pearson's coefficient. I name you the Go-to person for all my stats queries. :). Its tough coming back to this after so many years of being away from numbers and stats. Thank you ever so much.

I have spent a week trying to figure this out, even used a scientific calculator, and still could not get the correct answer, figuring it by hand was a last ditch effort and your explanation made sense and I was able to finally comprehend this, thank you

This was a much simpler and clearer method than what I remember learning in college. I understood everything. Thank you so much for sharing this video

Very informative for a layman, thank you! I've watched the Pearson and the Spearman correlation videos and now have a clear understanding of how to calculate correlations for a task I'm doing.

i have an exam in 2hrs time and i had never understood this in class but thanks to you now i get it FINALLY!!!!! Thanks alot. God bless you

Thank you; Sir, for making such an easy explanation of how to do this. I was so lost within my class, not understanding, however, your step-by-step review; was amazingly put together.

Thank you! You are helping an “older” student in Orlando, Florida, USA, get back to university and finally get that Bachelor of Science 😁

Thank goodness I found this! Dr. E. is saving me as I work my way through a Grad stats class after not taking a math or stats class for years!! I haven't used stats in a very long time... these videos are a saving grace for anyone needing extra support ! Thank You!!!

I just want to say thank you. I hv exam and this saved me. RU-vid is just the plug for everything u want.

You literally saved me. I was so confused before this video and now you have made me understand this so much better. Thank you so much

Needed this! I just started taking a bio course and this is coming up and I had NO clue what she was talking about. Thank you!

4 years have passed since this upload yet i just wanna say this truly helps me alot😢 thanks u

Finally someone that speaks English! Thank you!

I have been working for my test for two days of distance study and now i really truly understand only 10 mn ahead while my teacher explained it 6 hours but nothing clear , thank you sir may God bless you ,keep it

Eugene, you have no idea how useful this is. Thank you for the time and effort invested. Thank you so much.

Thank you so much for this video, I've watched a lot of videos regarding to this topic and my head is a total mess for the past 5 hours of sitting and finding clearer and much better explanation for this one.

Sir, I greatly appreciate this with all of me. Bless you!

Your method for explaining the lengthy calculation process is truly impressive!

Writing about this in 4 hours time, let's just say you saved me. Thank you

This is by far the best video I found on the web. Thank You so much.

THIS VIDEO LITERALLY SAVED MY LIFE THANK YOU SO MUCH 🙏🙏🙏🙏🙏

I have a midterm exam after half an hour and on behalf all the stat students I would like to say thankyouuuuu soooo much iilove you

This tutorial video is a plus. Just got to listen to it right before my IA. Thanks Eugene.

Thank you so much, I did not have access to a graphing calculator and needed my linear regression for a formula, this taught me perfectly!

This actually makes sense! As an Audio engineer there are obvious correlations. Thanks champ!

Thank you Sir Eugene. You helped me treat my data. You teach briefly but clearly.

Thank you for making it simple. You're a true teacher.

Fabulous lesson, getting me through medical school. go raibh mile maith agat.

Thank you. You’ve saved my statistics exam 🙂

Thank you so much! We went through several different formulas in class and I had become so confused. You've broken this down so clearly. Many, many thanks.

Thank you so much! Very clear and straightforward. Easy to follow. I feel ready for my exam tomorrow afternoon

You have no idea how much this just helped me. Thank you!

I have an online stats course and this is the only thing that has helped me. Thank you so much.

This is a great video. The instructor explains the equation very well and gives a great step by step explanation on how to use it. This video helped my understanding of PCC immensely.

this video was very helpful, i learnt how to solve this to teach it to my wife, thank you

Thanks a lot I had found difficulty in understating this in class. Thanks again sir

My professor didnt even explain how to do this he just expected us to know so thanks for this!

this is way more clear discussion than my istructor did thank you

omg this was so easy to follow thank you so much, i was basically pulling hair out trying to figure this out on my own

This video is a godsend! Thank you so much! I'm taking graduate level statistics after not taking a math class in 15 years! I needed this because the book didn't explain it and the study guide was no help! Happy New Year in 6 hours...

I'm 61 and will need this for work I am pursuing in science. In baseball, you could understand how a team will be expected to perform. Nothing personal but many people might not understand that what you showed is just a basic application of a mathematical principle. And it will matter when they put it to use.

I really love your videos. Your demonstrations, explanations, and examples are more helpful than you know. Thank you very much!

Thank you for simplifying this work. I was about to give up

this is incredibly helpful and so much easier to understand and apply than anything else I've come across so far - thank you

Greetings from India, I am a psychology grad student. Your videos proved very helpful to me in understanding the basics...

Tgabk you so much for this. Taking an exam tomorrow, this has helped greatly. Hoping to update with the good news

Sir thank you for making this video you saved another student.

its an outstanding video, i never do this even at high school but its easy to understand it. thanks a lot Sir

big up yourself, you made it so simple and easy to understand!🔥

Im struggling with our research right now. Thank you Mr. Eugene this was a great help

Thank you for this explanation. For someone that struggles (which is an understatement) with statistics, this helps me to actually understand.

you're godsend. i love this video, it literally helped me answer my finals.

I used to think this stuff was jibberish😂.. But thanks to your explanation, I understand it well now.. Thank you so much for this video sir.

Thanks soo much man life saver better than my professor for sure

you saved my life ilysm

Thank You so much man, Sometimes in math it comes down to how simply you organize your work which makes the difference between getting lost or understanding!

U really came in clutch for Year 9 KHS students

I've been coming back to this video for like four years now because I keep forgetting how to calculate this lol

This video saved my life. Thank you!

Very useful video, I finally understand how to calculate correlation coefficient. My professor did not explain it clearly and it seemd very complicated, however after watching this video I think I'm ready for my exam!!!

you saved my life thank you so much

I hope you do more series about calculating by hand. You’re great at this.

Thanks from Canada, Eugene!

Really straight forward no added rubbish. Thanks!

i passed my statistics final thanks to this video! thank you so much!!!

Props to the people who invent these formulas

Awesome, this helped me because I had no idea what to do

This video is heaven sent.
