Associations in Data
Lesson 1&2
8.SP.A.1: Construct and interpret scatter plots for bivariate measurement data to investigate patterns of association between two quantities. Describe patterns such as clustering, outliers, positive or negative association, linear association, and nonlinear association.

3. In a different color, plot the height and hand span of each student in your class, making a scatter plot of the heights and hand spans for the entire class.
4. Based on your scatter plot, answer these questions:
Yes, taller students tend to have greater hand spans. On the graph, as the heights increase, the hand spans tend to increase as well.
No, the hand span is not a linear function of height. (no straight line)

Plotting Data
I can draw a scatter plot to show data that has two paired variables.
Histograms or box plots are useful when displaying numerical data from a single variable.
Scatter plots are more useful when looking for a relationship between two variables that produce numerical data.
Two measures about a single person or object.
