Types of Data
Data is another word for information
There are two types of data: Qualitative and Quantitative
Qualitative data is to do with things or descriptions (quality)
Quantitative data is to do with numbers and amounts (quantity)
There are two different types of quantitative data: Continuous and Discrete
Continuous data can take any value, along a sliding scale (eg. height or weight)
Discrete data can only ever take specific values (eg. age or number of children)
