Unit 6 - Lesson 2 - Grade 8: Illustrative Mathematics

Lin surveyed 30 students about the longest time they had ever run. Andre asked them about their favorite color. How could Lin and Andre represent their data sets? Would they represent them in the same way? Why or why not?

What types of graphical representations could be used to show the class’s height measurements? Make a graphical representation of the class’s height measurements.Choose a color and use it to plot a point on the coordinate plane that represents your own height and hand span. Then, in the same color, plot a second point that represents your partner's height and hand span.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.

Do taller students in your class tend to have bigger hands? Explain how you know.

Is hand span a linear function of height? Explain how you know.
