Lesson Details

Key learning points

Primary data is collected first-hand, secondary data was collected by someone else.
Qualitative data is non-numeric information, quantitative is numeric information.
Quantitative data can be either discrete or continuous.

Common misconception

Pupils may think that primary data means data they collect first hand (and no one else can collect it).

Primary data refers to data that are directly collected for specific use in an investigation. This means that a team of researchers could collect the data for you for your investigation and this is still primary data.

Keywords

Primary/secondary data - Primary data refers to data that are directly collected for specific use in an investigation. Secondary data refers to data that were previously collected for a different or unknown purpose.
Qualitative - Qualitative data are data that are non-numerical, and usually describe a quality of something.
Quantitative - Quantitative data are numerical data that can be counted or measured.
Discrete - Discrete data can only take specific numerical values.
Continuous - Continuous data can take any value on a scale to as much precision as we can measure it.
