Discrete and continuous data Drawing pie charts and frequency diagrams Work through all the sections or jump down to the ones that interest you. 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 .
The following examples will show you the difference between the two. Look at the set of data below. This data set shows a group of discrete data. Shoe sizes are a classic example of discrete data because sizes 39 and 40 mean something, but size 39.2, for example, does not. The data set shows a group of continuous data.
