General KnowledgeStatic General Awareness
- APie chart
- BScatter graph
- CBar chart
- DTriangular graph
Explanation
A scatter graph (scatter plot) is the standard tool for showing how two sets of numerical data relate to each other, since each point plots one variable against the other and reveals correlation, clustering or trends. A pie chart shows composition of a whole, a bar chart compares categories, and a triangular graph is for three-component proportional data. Hence the scatter graph is most suitable for relating population size and number of services.
