What does r stand for in math
We know that nCr n C r counts the number of ways to choose r r objects from n n objects, without caring about the order you choose them from. But suppose now we want to care about the order. There are r! r! ways to order the r r chosen objects. So we have. nPr = nCr × r! n P r = n C r × r! Recall the formula for.The 3 R's stand for: Reduce, Reuse, and Recycle. Perhaps the 3 Rs now stand for something else, but originally, the 3 Rs stood for (R)eading, w (R)iting, and a (R)ithmetic.

If r = 0, this means there is no linear correlation. Note: If r = 0 this does not mean that there is no relationship whatsoever, it just means that it is not linear. It could be a quadratic relationship. That can be left for another blog post. Another important thing to note is that r DOES NOT represent the slope of the line of best fit.Pearson Product-Moment Correlation What does this test do?
