How does a horizontal bar chart differ from a vertical bar chart?

1. It shows data over time

2. It allows for more categories to be displayed

3. It presents data horizontally instead of vertically

4. It is only used for numerical data

The correct answer is: It presents data horizontally instead of vertically

A horizontal bar chart presents data horizontally, which distinguishes it from a vertical bar chart that displays data vertically. This orientation can enhance readability, particularly when dealing with long category labels or when comparing a larger number of categories. In cases where the category names are lengthy, the horizontal format allows for better visual representation since it can reduce clutter and make the labels more legible. The other options refer to characteristics that are not exclusive to horizontal bar charts. For example, the representation of data over time can be managed by various chart types, including line charts, which are often more suited for time series data. The aspect of allowing more categories to be displayed can depend on the available space rather than the chart's orientation itself, as both horizontal and vertical charts may have limitations on how many categories can be effectively shown. Lastly, while both horizontal and vertical bar charts can represent numerical data, they are not limited to numerical datasets. They can also effectively represent categorical data, making the statement about being used only for numerical data inaccurate.
