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.

[@pgurl4862]

This is by far the BEST explanation of the correlation coefficient that I have come across. Thank you!!!!

[@cylurian]

Thanks. Please share with your friends. Also more videos on statistics at ua-cam.com/play/PLwkuA9oqOxXSQZ7s97Z2ona1VNmiwyUlR.html

Thank you SO much for this video. It was clear and helpful. This is how simple learning should be. I've been struggling with this particular formula (and math is NOT my strong point) but you've made it so easy, and it's all finally clicked. Thank you!

[@SankiMend]

This tutorial gave me a clear idea.Thanks alot.

[@loganp2896]

Thank you! You explained 4 pages of nonsense from my stats textbook in clear and concise language, you should be a professor.

Awesome Example! Extremely Helpful and easy to follow! Thank you.

[@batteryman2852]

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.

[@usamayousaf9195]

[@cylurian]

Great. I hope you do well in your math.

[@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😊😊

[@maerionbright809]

best tutor. thumbs up

The closer a number is to +1 or -1, the stronger the relationship is.

[@bernardchinsamba1111]

What a good explanation

[@cylurian]

Thank you. Please share with others.

[@haton3847]

You saved my life

[@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.

[@carajaclasses]

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?

[@lovegodmyself]

Thank you so much! This is really really helpful and easy to understand, I am really grateful to be able to find this, thanks again and again for your video and effort!

[@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

[@cylurian]

Thanks dude. Pass the love with your other friends.

[@JourneyOfSciences]

This is really helpful

[@cylurian]

Thank you. Good luck.

[@cjhall19]

Thank You!!!! Great Video!!

[@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.

thanks dude you've saved me

[@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.
