Calculating Correlation (Pearson's r) 

There is an error in the calculation of degrees of freedom. Please watch the corrected version at ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-k_dcsZ_0uNI.html. The N is 7, not 14. I counted the number of scores (which is typical in other calculations), instead of the number of cases. In this example, the df is indeed 5, meaning the critical value is 0.669, which is greater than the calculated r of 0.62, meaning we accept the null = no correlation.

I'm in 12th grade and had the lead our group in doing our research study, as someone who had zero ideas on how to conduct one, what statistical tool and method to use, this video saved my grades from failing. THANK YOU SO MUCH

You are the best person that has ever explained this. Now I do not feel aloof anymore

14 minutes made me understand what I could not get in 7 days! Thank you Patricia for publishing this video.

Like Albert Einstein once said, if you can't explain it in a simple way, then you don't understand it well enough. Thank you,, Patricia, Jenkins, because you made me understand the concept so well. I look forward to more videos from you.

This is amazing. I am a PhD student ready to conduct my correlational study and only now (after you explained the definitions and terminology in a mathematical context) I have clarity and can finish writing my proposal with confidence. Thank you for this

Hi, Patricia. I must say your teaching style is highly commendable. I will certainly refer you to family and friends, because anything that is commendable is surely recommend-able.

You are a great teacher 🔥🔥🔥. Only 14 minutes, very beneficial

I’d like to give this instructor her flowers 💐🌺 🌸 Ty

This is excellent. I will suggest to my students. Also, P. Jenkinson's vocal delivery is very warm, calming. I feel students will respond well to her lecture. Thank you so much for this lecture. best--Dr. LLM

BEST VIDEO ABOUT THIS TOPIC EVER. THANK U MA'AAAM I HAVE MY FINAL EXAMS LATER YOURE A HERO, ANGEL, AND GODSENT. ILYSMMM

Thank You.....Had to follow step by step and practice. Then input in spss and it gave me the exact outcome PHEW. at last I got a good expalnation. Thank you Pat.

Super helpful! Got the song stuck in my head all day😂

hi there Ms. Patricia! You're totally awesome. thnx for sharing your expertise

Plainly explained. The steps are easy to follow. Simplicity at its best.

it was very help ful to me,true definition of a teacher

It helps me a lot. I thought it is very hard but this video helps me to understand it in a very simple way

So much videos but this is the best among them!!!

Thank you very much. The way you break down on the presentation really helps. Thank you again. 👏

Clear and easy to understand. Best stats video I've seen by far!

Amazing informative sharing..

I also have lyrics to add to your and your professor's brilliant song. They are as follows: If any of your students wish to declare their love for each other during your lesson, they may wish to do so with the following words: The greater the *number / The brighter love's ember / Darling, don't you see / How much I adore thee? / 'Cos our hearts lie so near the magic line / So this Feb 14th, won't you be my Valentine 🌹? *in context, "number" refers to the coefficient of correlation, whereby a higher positive correlation coefficient indicates that the 2 of them are highly compatible

So very helpful e-tutorial. Very best Prof. Jenkinson

Thank you so much for providing such knowledge for free.

Is the number of observation 7 or 14? There are only 7 data points??

You are amazing thank you. Been confused on how to do it but I understood it well~

Congratulation for the precise explanation

Best way of teaching.........thax

Very nice/under-stable presentation.

best explaination so far I checked out about regression. Thanks Patricia.

Very benificial thanks for teaching such s brief and easy way to learn basis concept

That was soooo helpful. I love the way to broke that down I could actually understand it. Do you have any videos explaining Regression and ANOVA or SPSS ?

very informative and simple explanation. thank you

The Training video is very simple and easily understandable .Thanks for publishing a good training video

You helped me a lot thanks

Thank you very much.

Best exposition I have come across. Thanks

Thanks in a million. Where have you been all these years!

Thank you so much!

This is great Ma ❤ The timing so good

wonderful. please continue

The explanation is excellent👌👌👌👍👍 but faced a problem reading down the text. Because of translation strips running whole over the session..

Love the way you teach, thank you!

Very good explanation.

Greatly explained

best lecture

Sooo helpful...thanks for the tutorial😊

You knocked it out of the park - Awesome

Awsome lecture. Thank you!

Thank you!

Thank you very much indeed. You made my assignment easy.

Would it be correct to say that the essence of Pearson's formula when stated in words is: For the denominator see how far all the X's and how far all the Y's vary from their average. The larger the variation of all the X or all the Y or both makes for a larger denominator. For the numerator, see how much each (x,y) set moves in tandem. (X1 is increasing while Y1 is increasing for example) . If in many of the sets x and y are both moving by large amounts in the same direction as in the other sets you get a bigger number than if they are moving in different directions in some sets vs other sets. If the amount of movement in the same direction between the (x,y) sets approaches the amount of movement between the Xs and Ys seperately then you have found correlation.

Thanks, Ms. Patricia.

This extremely helpful, very clear step by step explanation. Thank you very much

really nice way to explain the subject and make it great you did a great job

useful content, thanks

That was an excellent explanation and example. Thank you!

That was a fantastic explanation, thank you!!

Well explained

THANK YOU VERY MUCH. PAPASA NA KAMI SA THESIS YEHEY HAHAHAHAHAHA (BALIKAN KO TO PAG PUMASA KAMI) AMEN!!!

THANK YOU SO SO SO MUCH! You explained it perfectly making it seem so easy to me :) Made me feel like a genius after I found that I got the exact number that popped up on the automatic answer in excel! Thanks for the video! Today I have a Biology IA due and this just saved me! (it's 4:00am here right now) *#IBLife*

First, thank you for your help Can I ask what is the difference between ( scatter diagram, Karl person's coefficient of correlation)

Very nice teaching

Thank you..👍👍👍

In excel the correlation is not significant at 0.05. The p value given in Excel is 0.136 which is > 0.05 so we accept H0. So the correlation is not sig. Can you please explain to me why is this?

Easy to understand

Good explanation

Very educating. Thank you.

Your ending song was great. Although I am a postdoc, kindergarten pedagogy still works HA HA HA

How did you find the pearson's r? plsss helpp me

you saved me bro

Fantastic! Keep educating.....

Thanks. Very helpful and I could understand it!! :)

very good video

thank you so much you really explained it well in a nice way

Useful video and well explained. However, there is a mistake in the DF calculation. Your sample N is 7 not 14.

Great explanation! Thanks

Thank you so much 💓

Hi...but i thought you are mistaken on 5th column that not the summation of them

This was exactly what I needed thank you so much

This is great thanks so much I was helped

This helped me so so much; thank you!!

Very helpful. Thank you

This was so great... Thanks a lot 👍

thank you very much for the excellent presentation. only one point I couldn't understand i.e. when we are comparing to critical r, what is; assume alpha level =.05 for a one tailed test?

Thank you mam.

Awesome

Thanks for the very helpful video! 😊 but I have a question. Is this applicable to a sample size of 60 or even more?

Thank you soooooo much. My professor is more interested in showing us the computer work and not so much the long hand. Sadly MyStatLab loves math problems and doesn't care about JMP.... thank you, thank you, thank you

Thank you. It helped

thank you queen

really good video, thank you so much!

The greater the *number / The brighter love's ember / Darling, don't you see / How much I adore thee? / 'Cos our hearts lie so near the magic line / So this Feb 14th, won't you be my Valentine 🌹?

Great

Excellent! Patricia.

Why is the degree of freedom equal to 14-2 and not 7-2 ?

I think you mean epsilon not sigma, but this was great thanks

Just curious...for correlation, the degrees of freedom is indeed n-2. I thought that for correlation purposes, n was the total number of paired data points, not counting each part separately. Since we have 7 students, wouldn't we only have 5 degrees of freedom, not 12?

♥️Wow thanks a lot

The best 🎉
