Hi everyone. This video will show you how to calculate the correlation coefficient with a formula step-by-step.

[@burnwolfpromotions]

This video was exactly what I needed thanks so much

[@cylurian]

Thanks. Don't forget I have other statistics videos for you. Please subscribe to my channel - @t

[@gauravsapkota1269]

Life saver!!! You explained so much better within 9 minutes than my lecturer did in 2hours 🤓👏🏼

[@LeylaThaSavage]

This is a more comprehensive video on the correlation coefficient. I watched another video and she totally forgot to mention the square root. I think its important to go through every step in a how to video. Thank you. I understand this now.

[@nesha1011]

The simplicity of this video is great! I'm doing a quantitative statistics class and my professor made this so complicated! Thank you.

[@rachelrayl9405]

Thank you, I thought the video was very clear and to the point. You sir, have restored faith in the human race.

[@andrewthompson4228]

That is the most brilliant, simple and applicable way of explaining it. Well Done!!

[@ryanz9779]

Thanks for the video. It is still the best after been published for 10 yrs!

[@cylurian]

I appreciate that. Good luck. Tell your friends.

So glad you told that you had to multiply the square brackets, was wondering for a while there :P , at least it make sense now. and maybe i can understand signal filtering one day, since the N array can be sample of anything.

[@imtiyaz1763]

very easy explaination and cleared

[@mehwishshah4979]

In correlation we don't know about whats the dependent and what's the independent variables... When we know we use regression... We use correlation just when we dont know which one is dependent and which one is independent variables..cylurian😊😊

Hi I liked your lecture very much- I’m also into Online teaching- I wish to know how you got this character by character animation? Did you used writing ✍️ stylus and any animation technique?

Thanks. Please tell your schoolmates about the video.

[@Brokenlikefour]

Good vid, but you could also have thrown in the coefficient of determination in there by squaring R, it's one step and pretty important for further interpretation

Thank you sir for the clear explanation.

[@hus390]

Explaining the results more. (*0.81) means a stronger correlation because it's close to (1). If its (-1) or closer to it, then it's also a strong correlation. Zero or very close to zero means no correlation.

[@cylurian]

Hello ATM. Good question. The range of r goes from -1 to 1, including 0. When the trend of the data is negatively correlated meaning the data points are trending downwards, then the r value will be negative, but you have negative values from -1, -0.9, -0.8....-0.2, -0.1, 0. Which negative number will it be. Well that's where the definition of correlation coefficient comes in. Correlation coefficient is the strength and direction of the data. I just talked about the negative trend, which is "direction" and thus the r value with be negative. Now, we need to know the "strength". The strength is how "tight" the points are together. The more spread the data points are, then r will be closer to 0. If the data points are closer together then r will be closer to -1. When r = -1, then all the data points are aligned together in a negative trend. This idea also occurs the other way, when the trend of the data points have a positive trend, and thus r is positive. The more the data points are aligned then r will get closer to 1. Good luck ATM.

[@itzayesha1389]

thank u very much you are a great man...

[@jacintaamaka174]

God Bless u!!! This help me a lot, teach more better than my teacher!!! Pls did I need to put 0.811 or just .811?

[@cylurian]

Hi Jacinta. I'm glad it helped. Most teachers will tell you 0.811. Though .811 or 0.811 is correct.

[@brendaramos2169]

Thanks! totally helped me out !

[@cylurian]

No problem. Come back and watch another video if you need it for statistics. Take care.

[@Berrypunch3]

THANK YOU SO MUCH!!! This really helped me prepare for my exam!!! 😀😄🙏👍

You're welcome.

Thanks!

[@paulangelo8041]

10 years later and you're still replying? lol

[@deniferi632]

You were explaining it well but should stay longer at the end. Explain what those numbers mean. Explain how to fit it in an assignement. Explain it to the non-technical audience.

[@cylurian]

These videos are meant more for step-by-step instruction on the correlation coefficient. I do have other videos but they are hidden away for they are only meant for my students. As you probably already know, correlation coefficient is just really a trend between two variables. Of course it’s the strength and direction of the data. Given the fact that in algebra you use two points for a line, and statistics you have to use all the points to determine if there is a relationship between the two. Which leads us to the next topic regression. With regression you have to use all the points as well to determine the best fit line.

[@rohitrockz7641]

Excellent sir thanq it's more useful to students

[@_candicescreations]

Thank you very much! Made my day!

[@malikapollard3618]

I understand everything in this video. I do have a question. My teacher always asks us to explain why the correlation is strong. And since i missed a view cllasses i have no idea how to properly answer this question.

Greeting from "INDIA"

[@Cory_]

Thanks man! Really insightful and easy to follow!

[@estherwanjiru6001]

Thank you I love it

[@mokogintanurarife.6570]

Woah thanks, hahaha can't learn in school, but this is good hahhaa

[@totorok2767]

This has been very helpful to me. Thank you! But is it possible to find the correlation coefficient if the there's only the x data?

[@cylurian7603]

No you can’t. You need two coordinates, x and y. The idea of correlation coefficient is the relationship between x and Y. You have to have two of them so that you can compare one with the other. Correlation coefficient allows you to understand quantitatively if one variable is related to another in a sense that one is affected by the other. For example say the temperature goes up then you would sell more ice cream. X would be temperature and why would be how many ice cream‘s you sold. Now every day would be a pair of data. One day let’s say the temperature was 21°C and you sold 50 ice cream‘s. That would be two data points. Then the next day the temperature was 30°C and you sold 280 ice cream ‘s. Now you can see a relationship. The hotter it gets the more ice cream you sell. You’ll need a lot more data to make sure that this is a relationship. R will give you a value that will tell you if there is a trend. Also it will tell you how well or how strong The two are related

[@X4ngu]

awesome tutorial !

too good n simple..thnk u so much :)
