Michael is a Professor of Mathematics
with DeVry University and is going to prepare a series of charts which
show the academic success rates of students for each earned letter
grade including A, B, C, D, and F letter values. The charts will be
presented to all math majors during a special scheduled session and then
to all non-math majors during other scheduled sessions. Before any
presentation, Michael had a meeting with the Academic Chair, Sally, and
the following concerns were expressed. You decide to help Michael create
a document formalizing suggestions based on your extensive experience
working with Microsoft Excel charts.
Part 1: The Academic Chair
loves all charts; however, she instructs Michael to consider if all
charts are appropriate for non-math majors. For example, Michael
created some box and whisker diagrams also known as Box Plots. Non-math
majors may not understand how to read these types of charts. What other
types of charts could Michael consider creating to display academic
success rates for earned letter values including A, B, C, D, and F
grades and why?
Part 2: Michael also created some histogram charts
which are simply customized column charts. Since normal column charts
are used often even for non-math majors, would you suggest that Michael
also show the histogram charts to the non-math majors? Why or why not?
Part 3: Michael also used some well-balanced creativity using color
choices including light earthly tone reds and greens. Should Michael
consider that some audience members whether math or non-math majors may
be colored blind? Why or why not?
