A graph titled Teacher Age versus height has age on the x-axis and height (inches) on the y-axis. Points are at (22, 66), (28, 70), (35, 62), (42, 72), (60, 50) and (59, 69).
She wants to see if a teacher’s height depends on his or her age. What did she do wrong when she created the scatterplot?
She mixed up the independent and dependent variables.
She labeled the x-axis of the scatterplot “Age” when she should have labeled it “Teacher.”
She plotted the point (36, 62) when she shouldn’t have.
She mixed up the x- and y-coordinates of the point representing teacher 3.
