Summary

Discrete and continuous data

​​In a nutshell

There are two different kinds of data: discrete and continuous. Different diagrams are used depending on the data type.


Different kinds of data

DEFINITION

EXAMPLE

Discrete

Whole number data that is counted, not measured

The number of books on each shelf in a library

Continuous

Measurable data that could take any value

The height of students in class


Displaying different data types

Deciding the type of numerical data you have allows you to decide which chart, graph or diagram to use. 

  • For discrete data the best type of diagram to use is a bar chart.
  • For continuous data the best type of diagram to use is a line graph.
