You have just finished a simulation exploring how to create, interpret, and make predictions using scatterplots. The data in scatterplots can provide a visual indication of whether a relationship exists between two variables, and if there is a relationship, it can also provide information about the strength and directionality of that relationship. Answer the following question regarding your experience with the simulation. How can you tell if a relationship between two variables is positive or negative based on looking at a scatterplot of the data? Describe what the scatterplot looks like for both a positive relationship and a negative relationship
