What is the difference between discrete and continuous data? (bar charts)

Discrete data
This data set shows a group of discrete data.
This is called discrete data because the units of measurement (for example, CDs) cannot be split up; there is nothing between 1 CD and 2 CDs.

Continuous data
The data set shows a group of continuous data.
This data is called continuous because the scale of measurement - distance - has meaning at all points between the numbers given, eg we can travel a distance of 1.2 and 1.85 and even 1.632 miles.
Continuous data can be shown on a number line, and all points on the line have meaning and are different, but with discrete data only certain values have meaning.

Think of it as five or above give it a shove. change the 5 or above to the right to a zero and add one to the number on the left.
