1 9.1 Constructing Scatter Plots A scatter plot is a plot on the coordinate plane used to compare two sets of data and look for a correlation between those data sets. An association is a relationship or dependence between data. For example, the price of oil and the price of gasoline have a strong association. The daily price of oil and the number of penguins swimming in the ocean on that day most likely have no association at all. However, to find this association we need to make a scatter plot. Start with the Data Before we can make a scatter plot, we need two sets of data that we want to compare. For example, we might compare the number of letters in a student s first name and their math grade. Do people with shorter names tend to score higher in math? Do people with the lowest grades have longer names? These are questions of relationship, or correlation, that we can explore with a scatter plot once have some data. That data set might look like this: Name Nichole Josiah Kame Gungar Roberto Frank John Herman Sami Daimon Letters Grade Name Yolina Johanne Karolinea Kurt Addison Ian Dennis Ophelia Kristina Bradford Letters Grade Prepare the Coordinate Plane Math Grade Letters in Student s Name Now that we have our data, we need to decide how to put this data on the coordinate plane. We can let the!-axis be the number of letters in a student s name and the "-axis be the students overall math grade. Once we have decided this we should label our axes. Next we ll need to decide on a scale and interval. The scale is the low to high number on the axis and the interval is what we count by. Notice first of all that we re only looking at Quadrant I because we won t have negative amounts of letters or negative grades. Since the grades can be from zero to one hundred, we might choose to count by tens on the "-axis giving us a scale of and an interval of 10. Since the letters range from three to nine, we might count by ones on the!-axis. This gives us a scale of 0-10 with an interval of
