How to Use the Correlation Coefficient
The correlation coefficient formula looks pretty
Hi, I’m Ben Owens, math educator, here for About.com. In this video, I’ll explain the correlation coefficient. This is the correlation coefficient formula. I know it looks pretty overwhelming, but basically the correlation coefficient is a number that tells us how two things relate to each other. Say, for example, we have these two variables; The hours of TV watched versus a student’s GPA, and we want to see how strongly they relate to each other. With the data we have here, we can fill out the formula. So, now we can solve the formula. Finally, you’re left with (shorty explain final step), and the final outcome is... We can conclude that there’s a (strong) (negative/positive) relationship, which means... For more math tips, visit us at eduaction.about.com. Thanks for watching!
