Marcos reviewed all of the survey results, and threw out any data that was incomplete. We discussed how he should plot the data. Our independent variable is age, which ranges from 7 to 65. So we have a large difference in the upper and lower bounds of our domain. I instructed him to scale the x-axis by 2. Marcos decided that he would plot all three pieces of data on the same graph. Our dependent variables have smaller values, ranging from 1 to 11. The graph will look short and wide. Marcos set up the axis and started to plot points. He will continue next session.
