Question

The dots in dot maps are used to show the distribution of the variable over a particular region on the map. Choose some of the advantages of dot maps relative to other thematic maps.

• A. They are highly effective in showing density differences in a region.
• B. They are flexible and work with all kinds of data.
• C. They are simpler to retrieve data from the map.
• D. They work well in black and white maps.

Answer 1

Answer: (A), (B), (D)

They work well in black and white maps.

Relative to other thematic maps, dot maps are a simple yet highly effective way to show density differences in geographic distributions across a landscape. Data can be portrayed simplistically, even in a black and white map. While the versatility and easy-to-grasp nature of dot density maps is appealing, they have one fundamental drawback: they are terrible for retrieving numbers from a map. A choropleth map is a better option to retrieve numbers from a map.
