What Is Correlation?

Basic overview of correlation

[@tracy5155]

Thank you for this example of correlation!! I have read my text book and other TH-cam videos and the explanation has given me a clear understanding about what correlation is and how to identify positive and negative correlation. Great video!!

[@evankirry936]

Clear, concise, and effective breakdown. Thank you!

[@zalrawi80]

You are the best. You saved hours of researching this Stats class.

[@TheCALMInstitute]

I think this is a GREAT way to convey the information! kudos.

I use a Bamboo tablet and pen to do the screen writings, which I create in One Note and record using Camtasia. It might not be the best method but it worked for me. Good luck with your mini-lectures.

[@srvntoflrd]

thank you, this helped me out so much

[@bidybidybu]

Thanks for the explanation! I want to calculate the correlation between many factors which I enter daily. I got an android app called correlator, and I need to understand the difference between single correlation and multiple correlation which the app is showing to me... which one is better if I want to find the most correlated variable??

[@adithyani4]

Thanks a Lot.Simple and easy to understand.

[@liannegianellacamomot396]

Thank you for the interpretation.

Thank you very much. Quick & clear.

Okay I will be good looking forward to learning the torth iam creating a beater working way everybody will be able to understand what time it is Life Timing is all!! Faith forward by the Word IAM William

[@tahafarshbaf]

Thanks for complete explanation, does it always show always linear relation?

[@shahamel]

excellent explenation :)

[@mintoo2cool]

Thanks for this video. It was clear, concise and short. But, can you give me an example where i can get the intuitive feel of correlation ?
At 0:02 You said correlation shows how two variables are related to one another and how strong their relationship is to one another.
I fail to understand why the fourth figure (the curvi-linear one) has no-correlation. Clearly, variable X is changing with respect to variable Y (though not in a linear fashion). So there is a relationship between the two...

[@olivieros.1324]

This video is great, I loved the "M'kay" 1:19~

[@sandipani333]

[@sanjaybhalerao9437]

what type of correlation exist (weak or medium) if the "r" value is between 0.4 and 0.5 ?

[@billycat2168]

excellent video!

[@cindia1977]

thank u smelly cat

[@zorbcck]

great help thanks

[@wasif788330184]

it is really very good explanation, so could you please explain what is correlated response?

[@verydeeplines7398]

well done DrMaggard

[@christoffere425]

So a constant acceleration (i.e. when an accelerometer lays still on a table for instance), would be "no correlation"?

[@J3.S0]

uhhmm, about your fourth example of direction, if its a curve it is just called a non-linear. tried to research about it because my teacher told me that it still has a relationship but not linear. thanks though, you made it a little easier for me about correlation direction and strength

[@yakya128]

[@neallasta]

how do you know which variable is x or y?

[@cybrainx72]

So the slope of the line does not indicate the strength of correlation its only interpret direction of correlation ?

[@logofomosho]

very helpful thank you :)

Correlation is association. It may or may not indicate causality which is what what we need for a relationship.

[@mintoo2cool]

Okay, so what do we call the non-linear relationship between two variables ?

dunnnnnno

What is the applicaion of correlation plaese answer

[@divvy1400yam600]

Are the data sets the raw data or data after the raw data has been manipulated.
It seems the lateer.
What I am saying is using this vid in isolation is a little confusing.
I just know you agree. lol

its not linear, therefor there is no r. thats a parabolic relationship

[@cindia1977]

did not understand the weak-strong correlation

[@De4sher]

well by saying "correlation shows a relation between variables", then i simply can't agree that in the fourth drawing there is no correlation. there's no bijective correlation, i agree, but there's a correlation. If i see a parable in the drawing, there's definetelly something going on there, some way the variables influence each other. Not in a linear way, but correlations aren't about liniarity, but about influence.
So that fourth case - i don't agree with you.
