Topic: Data Presentation

 

Data presentation is the representation of data or information for easy reading and interpretations.

Data can be presented in pictograms, bar graphs or frequency tables.

 

A pictogram is the representation of data using pictures. For example, the following are types of vehicle that passes through a street in an hour.

🚲🚲🚲 = 3 bicycles

🚕🚕🚕🚕🚕 = 5 cars

🐪🐪🐪🐪🐪🐪🐪 = 7 camels

🚌🚌🚌🚌🚌 = 4 buses

🚚🚚🚚🚚🚚🚚 = 6 lorries

 

Bar Graph:

It is a way of representing information pictorially, using rectangular bars of equal widths. The spaces between the bars are the same. The height of the bar represents the number of times the event occurs. A bar graph can be horizontal or vertical.

 

The graph below shows the number of pupils who like different fruits.
