Visualizing part and partial correlations

“

- [Instructor] When it's a new topic for you this whole issue around R squared, and partial correlations, and part correlations can be confusing. Certainly it doesn't help, that sometimes to make an apples to apples comparison, we then get involved in part squared, or partial squared. I know when I was first learning this and I got a scratch pad out, I found that very helpful. If I was drawing this or looking at numbers and in order to keep everything the same, I would think of R squared, partial squared, and part squared. In that spirit, let's look at some Venn diagrams together and see if we can't get comfortable with the concepts behind these statistics. In the case of R squared, this is the one of course we're probably the most familiar with. It's gonna be the variance that the independent variables are able to explain in R squared. And, it's calculated as a ratio but we tend to go ahead and multiply it times 100 and think of it as a percentage. So, that's our R squared. So, when…
