The pictorial representation of numerical data is called _______
A. Picture graph
B. Graph
C. Pictograph
D. None of these

Hint: We will use the definition of each given option, that is, picture graph, graph and pictograph, to find the correct answer.

Complete step-by-step answer:
A picture graph is the representation of data by the use of symbols and pictures.
A graph can be of many types:
For example, line graphs help in showing the continuous data and helps in the prediction of future data.

Similarly, there are bar graphs in which data is represented in forms of solid bars and these are mostly used in comparison.

We also have graphs known as histograms to represent the data which are grouped in intervals.


All these forms of representation are collectively known as graphs.
Thus, the pictorial representation of numerical data is called graph.
Hence, option B is correct.
Note: One must know the definition of graphs, picture graph and pictograph to do this question correctly.
