Discrete and continuous data. Raw data is the information we get when we do a survey. For example, we might have a list of heights or shoe sizes. Data can either be discrete or continuous. 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. Bitesize CD store 31 January 2008
Continuous numerical variable A variable that may contain any value within some range is called continuous. For example, the time that the customer spends in the supermarket is continuous. Statistical methods that can be used for continuous variables are not always appropriate for discrete variables.
