Question

Which data are used to prepare dot maps?
A. Statistical data
B. Geographical data
C. Normal data
D. All of the above

Answer 1

Hint: The dot map is used to visualize the distribution and density of a large number of discrete objects while in contrast to a location map, not every single object is represented. It has only one icon representing a constant number of objects. Most often points are used, where this map derives its name from.

Complete answer: Option A: Data is individual factual information that is recorded and used for analysis purposes. This is the raw information from which statistics are generated. Statistics are the results of data interpretation and presentation, or
data analysis. These types of statistics are known as 'statistical data'. Statistical data is used to prepare a dot map.
Option B: Geographical data is related to the geography of the earth and can be displayed more often as maps. Other location data are geodata, GIS data, or geospatial data.
Option C: Normal data is data extracted or obtained from a population with a normal distribution. This distribution is considered the most important and most frequently used distribution in both statistical theory and application.
Option D: All the above types of data are completely different in nature from each other. Therefore they cannot be represented on the same type of map making option D the wrong choice.

Hence the correct answer is Option A: Statistical Data.

Note: A dot map is a map used to describe the geographic density and distribution of a phenomenon, where one dot has a value of a certain number. For example 1 dot = 5,000 people. Dot maps are advantageous because they highlight high-density areas at a glance, raw data can be mapped, and finally they are easy to understand.
