Question

Which of the following precautions should be taken while using dot method for map
A. The size of the dot should be uniform.
B. The distribution of physiography, water sources, transport system, etc of a region should be considered while placing dots on a map
C. While showing population distribution, rural population is shown by dots and circles are used to show the urban population.
D. All of 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 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 the dot, the density of the variable, and the scale of the map should also be taken into consideration.
Few things should be taken into account while using dot method:
The size of the dot should be uniform- In order to show the distribution of variables throughout a region, the dot should be of the same size so that it shows uniformity in the region.
The distribution of physiography, water sources, transport system, etc of a region should be considered while placing dots on a map- In order to show accuracy in a map, it's important to take account of the topography of that region.
While showing population distribution, the rural population is shown by dots and circles used to show urban population- In order to show two different variables, it's important to use dots and circles since it helps to differentiate between the two.
So, the correct answer is Option D.

Note: The following precautions should be taken while using the dot method: the size of the dot should be uniform, The distribution of physiography, water sources, transport system, etc of a region should be considered while placing the dots. While showing population distribution, the rural population is shown by dots, and circles are used to show the urban population.
