He asked three advisors to report back to him the next day
with a summary of the revenue data so he could understand
how his restaurants were doing overall. Each advisor chose a
different method to organize and represent the data. See
the three graphs they chose.
Which advisor do you believe organized the data in a way
that would be useful for the owner? What information can
easily be seen from that advisor's data representation? How
will this information help the restaurant owner? What's
something that can't be determined easily from the
representation you chose? Open the Notebook tool (13), and
write your answers.
