Questions 1. What are the variables in this situation? Which is the independent variable? Which is the dependent variable? In general, how do you determine independent and dependent variables for a given situation? 2. Create a scatter plot of the data. Be careful to consider which variable belongs on the x-axis and which belongs on the y-axis. Carefully consider the scales that you will use for each axis. It may make sense to talk this out with your partner or even another group before creating your scales.

Scatter Plots 3. Does there appear to be an association between team salary and total team wins? If so, describe the association, is it positive, negative, weak, strong? 4. Are there any data points that appear to be outliers? If so, which teams? How did you decide that they were outliers? 5. Do you see any clusters of data in your scatter plot? If so describe the clusters, giving salary range and range of total wins. Which of the sports shows the weakest association? 7. Based on the data from the four sports, would you say that there is a relationship between team salaries and wins in the sporting world? Explain your reasoning? To better answer this question, what other information would be useful? Whole class tasks: 6. Which of the sports shows the strongest association between team salaries and total team wins?
