RV coefficient
Okay, imagine you have a toy car and you want to drive it around. Sometimes you might push it really hard and other times you might push it gently. How far the car goes when you push it depends on how hard you push it. The rv coefficient is kind of like that, but instead of a toy car, it's a number that tells us how strong the relationship is between two things.
Let's say you have a box of crayons and you want to see if there is a relationship between the number of red crayons and the number of blue crayons. You could count the red crayons and count the blue crayons and then plot them on a graph. The rv coefficient would tell you how closely the points on the graph are clustered together. If they're very close together, then that means there's a strong relationship. If they're spread out all over the place, then that means there's not much of a relationship.
So, the rv coefficient is a way to measure how strong the relationship is between two things. Just like how pushing the toy car hard makes it go farther, a strong relationship means that when one thing goes up or down, the other thing does too.
