Question

How is the distribution through the dot method shown on maps?
A. Size of dots
B. Density of variable
C. Scale of map
D. All the above

Answer 1

Hint: A dot in a map is basically a symbol which is a circle of small size. Dots serve the purpose to show the distribution of quantitative characteristics. It can be used to show more than one element. A better vision can be provided by the dot method.

Complete Answer:
Maps serve the purpose of distribution of variables as well as to show the location of a place. In order to show the distribution in the map 3 methods can be used: Dot method, Choropleth method and Isopleth method By using statistical data dot map can be prepared, only data gathered through counting can be used. The dot method is considered a better method to show distribution since it is accurate as compared to other methods. Dot maps can be converted to Choropleth and Isopleth maps but Chloropleth and Isopleth maps cannot be transferred into dot maps. In order to show distribution by dot method, the value of the dot should be taken into consideration. For that lowest and highest values are taken into account. The size of a dot, the density of the variable, and the scale of the map should also be taken into account. The decision for the number of dots given for the value of the variable in the sub-administrative unit should be taken into account first.
So, the correct answer is Option D.

Note: Dot map serves the purpose to show the distribution of quantitative characteristics. The distribution through the dot method is shown on maps by the size of dots, the density of the variable, and the scale of the map.
