The table below shows the number of pages read and the score on the last test for nine students in Ms. Ferguson's reading class. On your own graph paper, set up axes, decide on a scale, and graph the data.

Pages read

on test

  1. Does there seem to be any connection between the number of pages read and the test score? Explain.

    One of your axes should be labeled ''Pages Read'' and the other should be ''Percent on Test''.
    Refer to the Lesson 4.1.4 Math Notes box for help with scaling these axes.

    Having trouble plotting your coordinate points? Refer to problem 8-48 from this lesson.

    Look at your graph. Do you see any pattern in the percent received on test as the number of pages rise?
    Remember to explain your answer!

  2. Do any points appear to represent outliers? Explain.

    Remember, an outlier is a number that is much larger or much smaller than the majority of data.
    Can you see any coordinate points that are a bit separated from the rest of the data?

    Point is an outlier. Can you explain why?
