Answer 1

Answer: (C), (D)

The correct options are
C The location of dots can be wrongfully infered as the precise location of the variable.
D There has to be a fine balance between the dot's size and dot's value.

Dot maps show the spatial distribution of geographical variables and their comparable densities. They are economical and easy to comprehend. But they have several disadvantages. Retrieving data in dot maps is difficult. They need a fine balance between the dots' size and dot's value. Dot locations can be inferred as the precise locations of the phenomenon being mapped. Also, when data is aggregated into enumeration units, choropleth maps offer a better solution rather than dot maps.
