Using scatterplot you can determine that the older you get, the less sleep you may need. You're most than likely getting less sleep than you probably should, you will see that this is a negative relationship. You can see as you move along the x-axis toward the greater numbers the points move down. This is turn means that the y-values are decreasing.Thus, making it like I stated prior- a negative correlation.

-help me describe how you I could use the 'scattergram' graphic to my advantage when I'm explaining this relationship to others.How would this help me to provide an example of a situation in which presenting a scattergram to a group of people would really help you to explain a relationship between two numbers?
