Understanding the strength of a relationship in scatter graphs is pretty easy once you learn how to do it. Here’s a simple way to think about it:
Direction: First, check if the points go up (positive correlation) or down (negative correlation).
Closeness of Points: If the points are close together and follow a straight line, the relationship is strong. If they are more spread out, the relationship is weaker.
Correlation: This is just a fancy word for how the points relate to each other. A strong correlation means the points stick close to the line, while a weak correlation means they don’t follow the line very well.
So, when you look at a scatter graph, think about these three things. They’ll help you understand how strong the relationship really is!
