Which of the following is not true about histograms?
a) the bars must touch each other.

b) a histogram may be symmetric or skewed depending on the selection of bin width.

c) each bin must have the same width.

d) histograms may represent categorical data.

e) histograms may have gaps or clusters.

The correct answer is:

D) Histograms may represent categorical data.

Explanation:

Histograms are used to represent quantitative data. As such, it does not represent categorical data.

The bars of a histogram should be equal width to accurately display the data.

Histograms may be skewed or symmetrical depending on the data.

If one particular bar has no data in it, there may be gaps in the histogram. There may also be clusters, dependent on the data.

We generally draw the bars of a histogram as touching, to illustrate that the data is not discrete but instead continuous.
