  2. What types of associations describe the relation between Bob's height and age?


    • negative, linear

    • positive, nonlinear

      Use the scatter plot of the height and reading level of Ms. Banks' students for questions 3 through 5.
  3. What types of associations describe the relation between height and reading level?

    • negative, linear
    • negative, nonlinear
    • positive, linear
    • positive, nonlinear
  4. Ms. Banks concludes that an increase in reading level causes an increase in height. Is her conclusion reasonable?
    • Yes, the points cluster along a line.
    • Yes, as reading level increases, the height increases.
    • No, an increase in height causes an increase in reading level.
    • No, association does not mean a cause-and-effect relationship.
  5. Add a point that is an outlier to the graph.
Answer:

  1. positive, linear
  2. positive, linear
