How to Test a Correlation for Significance

This video covers how to test a correlation coefficient (Pearson’s r) by hand. In part 1 we calculated Pearson's r and found it to be equal to -.90. Now we are testing it for statistical significance.

Thank you, both of the videos for Pearson’s r are excellent and the best explanations I have ever seen. Excellent, so thank you

I have a question... why did you not calculate the test statistic? It is step 3 in testing significance... I’m confused

Thank you for simple explanation!

Hello, thank you for your insightful videos, I learn a lot from them. I just wanted to request a course on Hotelling T2 test on SPSS, how and why it is applied to real data.

Thanks for the info! Very helpful! I noticed that there is no p value output when using 2D correlation to compare how similar two images are. Could you please explain why?

Could you explain how critical value table at 0:45 is drive from?

[@prashantbajracharya1752]

ikr..think its wrong

[@SCNE_Forever]

@@prashantbajracharya1752 ? Are you pointing out the 3?

[@jackionendino4293]

Thanks alot ❤️❤️

[@gerardsayomac1905]

to get the critical value, is the alpha equal to 0.05? or 0.025? because this a 2-tailed test..

hello, If i have a sample of a 100 people, the degrees of freedom would be 98, but somehow i cannot find dF of 98 anywhere online on the table...can someone help me?

[@margaretwatkins7008]

You’re confusing me. -.880 still in the red bracket.

[@jam4766]

Bro my r=4296
