Don't you have to divide the standard deviation by n-1 before square rooting it, so it would be SSx/n-1 ie, 10/4. Also for the final formula the denoinator includes n, making it n*SSx*SSy
He just simplified everything. Since if you divide SSx by n-1, that would basically mean that you would have to use Covariance instead of Cross Sum. What he did is basically cancelling n-1 from the numerator and the denominator.
Thank you so much, I cannot say why but I've had a hard time with this and some of the explanations went over my head, this was very simple and easy to understand the process. I have done a little tottering in math and I'm sure you cannot please everyone. This process really gets you on the ground and if you feel you need to go deeper you will be ready to handle it. Thank you again.
Thanks for the Calculations of the Correlation (Pearson's) that was awesome. I am really excited, it's very hard to understand when I see it in the first time. But when I got into it. That's easy to understand. Thank you so much.
so i added up the varience that's the the deviated numbers and tried squaring them but they'er not giving me the same X value, i've made sure of it to know where the error is from but i'm obviouslly correct because i've cross checked more than 7 times now.
The thing is, how do you find N? On the table there is (3,5), but I don't see the reason why the 5 of the third term, is N. It doesn't look to be a mean to anything either. Or, what is N really?
good explanation thnx. but are you recording this video being drunk? you are talking so drunk -styled, that it seems to me, that the next moment you will fall asleep
Love the constant reassurance: "it seems complicated but it's not that bad, let me walk you through it" Yes please walk me through it.
Thank you for presenting a simplified explanation of correlation. This helps a lot in my research. Keep it up!
Finally I got one of the hardest thing in stats! Thanks a lot!
Thanks to you. You made the hard thing easy and very interesting!
Why not show the correlation equation at the beginning?

Thanks for ur explanation on correlation and confections it add a lot of value to my learning

Wow- you explained it all in 1 module o..........o and made it so easy

Thank you so much! This explanation is much easier to understand! Helped save my grade hahah
Thanks! I like how you go step by step!
Thank you so much. It helps me to get down my assignment.

this is beautifully done
Thank you so much!! You made it so simple
this was so helpful thank you very much
What happen if the mean of x and y has decimal point? Plus the sum of all the mean of x and y is not equal to zero , 🥲🥲🥲
theres no interpreting in this video
This was very insightful
Many thanks for this video, is it possible explain how to find the spread between pairs ?
Such a helpful video. Thank you.
How do I calculate average correlation in excel (I have monthly performance data for 10 hedge funds)?
How to find the x and y sir?
wonderful.... a very clear explanation.
Awesome! great lecture!
If I put this in SPSS, it gives -1. How's that possible?
Thank you for a great video. Very easy to follow.
Thank you so much. It helped me a lot
Very helpful. Thanks!
THANK YOU SO MUCH!!! this is what exactly i needed. I followed along with a problem from my textbook and i got it right thank you!!!!

THANK YOU SO MUCH!
Simple and easy to understand.
That was a great explanation thank you
Thank you soooo much! Much appreciated!!
Thanks you. This is very useful
Thank you!
8:54 how did u get -9/10 =‐9
-9 / 10 = it's negative - 0.9 not 0.9
Thank you sir
Thanks so much
THANK YOU!!!!
Thank you
what happens when you have N=200
Very nice explanation, we can learn very easily in this way. Thank you.
You made it for me
when i move my mouse, i found it doesn't work.
crystal clear
THANKS
awesome
nice
this is impossible. I keot getting incorrect answers.
What type of witchcraft is this
good explanation thnx.
but are you recording this video being drunk? you are talking so drunk -styled, that it seems to me, that the next moment you will fall asleep
