20 students from a school were randomly selected to study the dollar amount that they spend on purchasing soft drink in a typical week. The data collected (in dollars):

$24, $35, $17, $21, $24, $37, $26, $46, $58, $30,
$32, $13, $12, $38, $41, $43, $44, $27, $53, $27

Some graphical representations are created based on the above data

Figures 1 to 4 are shown below.

Which do you consider an appropriate histogram? You can choose more then 1.


This is an actual quiz question but I find it to be so poorly worded I cannot understand a single bit. Can anyone help?

  • $\begingroup$ The histograms in the lower row are incorrectly drawn: they do not depict all the data, no matter how you interpret the vertical axis. $\endgroup$

1 Answer 1


I wouldnt say the question is poorly worded. It's just that the differences of the histograms are subtle, and can be missed.

The problem asks:

 Which do you consider an appropriate histogram? You can choose more then 1.

If you look at Figure 1 and Figure 2, at first glance they look identical. However, they have a major difference. Can you spot it? (Hint: Read the labels carefully).

Then between Figure 3 and Figure 4, you have an analogous situation. In each case only one is appropriate, given the data.

Can you take it from here?
