A real estate investment trust (REIT) owns first-class office properties in selected markets. According to its website, the occupancy rates last year for its holdings in four major cities are available below. Complete parts a through c below.
LOADING...
Click the icon to view the occupancy rate data for the four regions.
a. Explain why a pie chart would not be appropriate to display these occupancy rate data.
Why would a pie chart not be appropriate?
A.
The four percents do not comprise all occupancy rates, so their sum is a meaningless number.
B.
The given percents are not part of a single whole, so their sum is a meaningless number.
C.
The regions are categories, not quantitative values.
D.
The four cities do not comprise all real estate markets.

A bar chart shows the percent difference between the occupancy rates.
B.
It is easier to compare the occupancy rates between cities.
C.
The spaces between the bars make a bar chart easier to read.
D.
The use of a single color for the bars makes a bar chart easier to read.

D 8.8
E 13.9
a. Discuss whether a pie chart or a bar chart would be most appropriate to present these data graphically. Choose the correct answer below.
A.
While both charts clearly display the ratio of the units manufactured to employees, it is easier to compare the ratios across plant locations with the bar chart.
B.
While both charts clearly display the ratio of the units manufactured to employees, it is easier to compare the ratios across plant locations with the pie chart.

The graph consists of a series of plotted points connected by line segments from left to right. The points loosely form the pattern of a curve that starts at (1996, 14.5), rises passing through (1998, 20.0) to a maximum at (2001, 25.0), and then falls passing through (2004, 20.0) to (2006, 14.5).
