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.
The percentage of lemon in the juice is 10% The percentage of water sugar is (100-10)=90% The quantity of lemon in 20 liters of sugar water will be: amount=(percentage of lemon)/(percentage of sugar water)×(amount of sugar water) =10/90×20 =2 2/9 liters
