# Unit 11 Section 1 : Types of Data

This section is about the different types of data we can collect.
There are two main types of data: qualitative and quantitative.
Additionally, quantitative data can be divided into discrete and continuous data.

## Example Question

Below is a chart showing information about the two finalists in the men's Wimbledon championship 1998.
Think about whether each item of data is qualitative, discrete quantitative or continuous quantitative.

For example:
 Residence is a qualitative measure because it is not measured with numbers Double Faults is a discrete quantitative measure because it is numeric but can only be a whole number Weight is continuous quantitative measure because it can take any numerical value in a particular range
