The most suitable statistical diagram to show spatial distribution of population is a dot map. A dot map displays the spatial pattern of data by placing dots on a map, where each dot represents a specific number of occurrences or population. In the case of population, each dot could represent a specific number of people, such as 10,000 or 100,000. The dots are usually placed randomly within predefined geographic areas, such as cities, states, or countries. Dot maps are useful for showing the relative density of populations in different areas and can be used to identify patterns, clusters, and outliers in the data. Pie charts and divided circles are not suitable for showing the spatial distribution of population, as they are more appropriate for showing proportions or percentages of a whole. Line graphs are used to show trends over time and are not suitable for displaying spatial data.
