The (Pearson) Correlation Coefficient Explained in One Minute: From Definition to Formula + Examples

Many of those who have the best of intentions with respect to learning what the Pearson correlation coefficient is all about end up giving up quickly because in most cases, the explanations they come across are boring and overly-complicated.
Sure, this video could have simply involved me displaying the formula and repeating a textbook definition, it would have been the easiest thing in the world. However, I did my best to explain the Pearson correlation coefficient in such an easy-to-understand manner that it would be harder NOT to understand it.
In other words, this explanation of the Pearson correlation coefficient (with an intuitively displayed formula and straightforward examples) is no way an effort on my part to sound smart. My goal has actually been the exact opposite: helping people understand that statistics in general and the correlation coefficient in particular can actually be both easy to understand and... dare I say it... fun :)

OMG Seriously I used one minute to understand the concept!! Thank you so much!! This is like a miracle!!

[@OneMinuteEconomics]

I'm here to serve :)

[@rugvedkulkarni1593]

Thank you for posting this! It was very helpful.

[@OneMinuteEconomics]

You're more than welcome, really appreciate the kind words :)

[@daneshadavis8734]

I still don’t understand 😢

[@surajgangani9752]

Amazing man........Bravo !! Why am I going to college? You completed all the concepts in less than 30 min hahaha.

[@OneMinuteEconomics]

Thanks a ton for the kind words Suraj, comments like yours always make my day! :)

[@sonyamoran181]

Thank you, this was helpful!

[@OneMinuteEconomics]

Thank YOU for the kind words, Sonya :)

[@nishadhas9143]

Super bro superrrrrr superrrrrr good job all my doubts are cleared do more videos ......,........super

[@OneMinuteEconomics]

Very, very happy to hear that!!! :)

One Minute Economics needs your help! Please give me a minute (heh) of your time by watching the following video if you find the channel useful, literally anyone can help (either financially or by spreading the word about my work): kzbin.info/www/bejne/n6CTZZahppaLZ68

[@sampsuns]

I chose to watch your video cause it's short. But I find I have to watch another 2 videos! I should pick another video instead of watching yours. Because 1

[@OneMinuteEconomics]

I apologize for the inconvenience but the videos will, in my opinion, help you understand the concepts in a manner conducive to actually retaining the information. As opposed to acing a test but forgetting that information after a few weeks :(

[@user-vx5vp7ig4t]

nice

[@imomuganda]

Great video! Almost didn't like because the likes were a beautifully symmetric 555. Oh well.

[@OneMinuteEconomics]

Looking forward to the moment when it'll be time to ruin 999 :)

[@ChrisABaldwin]

Now they are at 666...which is symmetric but.....hmmm

[@coolzkabhijit]

did not understand inverse correlation example

[@OneMinuteEconomics]

1 = for each step forward I take, you take exactly one step forward / -1 = for each step forward I take, you take exactly one step backward :)

[@coolzkabhijit]

@@OneMinuteEconomics thank you

[@jacksonwolfe4405]

@@OneMinuteEconomics I don't believe this is an example of inverse proportionality. Inverse proportionality desrcibes a relationship that is hyperbolic in shape. For example the number of people working on a house and the time it takes to build the house are inversely proportional if it takes 1 person 10 weeks, it would take two people five weeks, 3 people 3.33 weeks, 4 people 2.5 weeks and so on. Inverse proportionality is non-linear, and pearsons correlation only describes the strength of linear relationships

[@AntiCx_edits]

@@OneMinuteEconomics damn your reply was even simpler than the video just shows how much u urself understand the concept very well

[@dr.nitajoseph3881]

I think in the video, the apples should appear instead of disappearing for inverse correlation. Right?

[@ronicaferreira2154]

huh?

[@OneMinuteEconomics]

If there's something you have difficulties understanding, let me know and I'll do my best to help, or perhaps someone else in the comments section will beat me to it :)
