Critical Background Knowledge- Students should know how to graph lines and write the equation of lines.

Content Objective: I can graph construct and interpret scatter plots. I can describe the relationships shown in a scatter plot (identifying patterns such as clustering, outliers, positive or negative association, linear association, and non-linear association). I can sketch a line of best fit on a scatter plot, and justify the location of the line. I can write the equation of a line of best fit. I can use the equation to make predictions. I can explain what the slope and the y-intercept mean in terms of the situation.

Language Objective: I know the definition of scatter plots, outliers, clustering, positive and negative association, line of best fit, and to justify.

Essential Question: How are important issues identify and explore through statistics?
