Spearman Rank Correlation [Simply explained]

Spearman rank correlation examines the relationship between two variables. The Spearman rank correlation is the non-parametric counterpart of the Pearson correlation. There is an important difference between the two correlation coefficients! The Spearman correlation does not use the initial data, but the ranks of the data.

These [simply explained] videos are so underapreciated! In only 5 min (or less, with a faster playback speed) I could understand what would take me some dozen minutes to hours. Thank you!

[qcube._.]

i have been studying from the contents you have made for 1 year now, the way you explain the concepts with example makes these topics so much easier to understand.
thankyou for your wokr

[donryangalan]

The best tutorial ever!!! pls keep on making more videos. very helpful especially for beginners❤❤

[marcus]

Excellent explanation! Thanks for making such great videos!

[vohiepthanh]

You explained these concepts too clearly!

[talicbronze]

What an exhaustive video! Thank you so much!

[chanishagarwal]

Really amazing video in less than six minutes you were not only able to explain the spearman correlation but t-test along with it. Thank you

2:00 Does the right graph have an error? It counts 12345 '7' 68 on the y-axis

Can you please do a video of kenduall's tau? Thanks for the great content.

[science_mbg]

this is really nice video and good explanation. Thanks for that but I did not understand for the p value calculation? What are the two things did you compare to get it? We were talking about test sample and population?

[docjaron]

Hi! Excelent explanation. What program did you use to make the slides?

[hekmatullahmuzaffari]

Hello! I rank the A 1, B 2, C3... For the grades of school children and their habit of breakfast are 1 for every day, 2 for most days, 3 for rarely.... 5 never... This ranks are correct? it right to find the correlation...?

[StefanQuandt]

Great explanations!
However, when talking using the term "positive correlation", I just wish you could add "which means increasing values of the independent variable correlates with increasing values of the dependent variable" 🙂

What do you do if you have tied ranks? I've been trying to understand my professor's slides on it and there's nothing on there about tied ranks and our homework has a tied rank. I'm so lost.

[benedictlim]

ahh no wonder i got confused at 3:09 I see that there is a 7-4=2 but to the left the original values are 6 and 4....so shouldn't it be 6-4=2? but anyways nice video

[corinneblair]

What is the best sampling method for Spearman? Quota, Judgement (Purposive), Systematic?

[DarkShadow]

If there are two people with the same age, should I write them the same rank or should I write one of them at a lower rank?

[lisanalghaib]

i really love u saying "Perason", like an "ũ" in portuguese in "Per".

[abrahamalvarez]

what if you have ties? do you use the same equation?

[sanyamsaxena]

What to do if 2 ranks are same in spearman correlation?
