The cicular graph is constructed based on percentages of each grade. Each percentage is then distributed over the full circle of 360°.
If there are twice as many of each grade, the percentage of each grade will not change, therefore the circular graph (pie-chart) will not change either.
Use the data in the grade-distribution table below to construct a circle graph showing the distribution of grade types in Ike’s class.
Grade..Frequency
A......2
B......8
C......11
D......2
F......1
How would the graph in Exercise 7 change if there were twice as many of each grade?
They would just double right?
