Describe how the graph below is deceptive. A bar graph titled Mike's Grade Point Average has first quarter and second quarter on the x-axis, and G P A on the y-axis, from 3.1 to 3.2 in increments of 0.05. First quarter, 3.1; Second Quarter, 3.2.
How would you change it so that it is not misleading?
a.
It appears that Mike’s grade point average for the second quarter is 3 times his first quarter average. Change the intervals on the vertical scale so they are consistent.
b.
It appears that Mike’s grade point average for the second quarter was significantly larger than his first quarter average. Change the width of the bars to display the correct scale.
c.
It appears that Mike’s grade point average for the second quarter is 2 times his first quarter average. Change the intervals on the horizontal scale so they are consistent.
d.
There is no way to change the graph so it is not misleading.
