## What do you mean by diagrammatic representation of data What are its objectives?

Diagrammatic Presentation of Data. Diagrams play an important role in statistical data presentation. Diagrams are nothing but geometrical figures like lines, bars, circles, squares, etc. Diagrammatic data presentation allows us to understand the data in an easier manner.

## What type of statistical data is best represented by diagrams?

Next, consider if the data best shown graphically or in another kind of display? In this case, since there is a large number of data values, the data are best represented graphically. Next, since the data can be used to show the frequency that people exercise, a histogram is the best type of graph.

## Which of the following is diagrammatic presentation of data?

Answer: Diagrammatic presentation is a technique of presenting numeric data through Pictograms, Cartograms, Bar Diagrams & Pie Diagrams etc. It is the most attractive and appealing way to represent statistical data. … Under Pictograms, we use pictures to present data.

## What is diagrammatic representation?

Representation of any numerical data by using diagrams is known as diagrammatic representations. … Diagrammatic representations use geometrical figures as diagrams to improve the representation of the data. Diagrammatic representations are like visual assistance to the readers.
