There are two types of secondary data, depending on the source of the data:
- Internal data sources : Information collected by the company or researcher’s organization (examples: customer database, sales reports, marketing analysis, your email, social media profiles, etc.).
- External data sources : Data collected outside the organisation (i.e. government statistics, media channels, newspapers, etc.).
In addition, there may be two types of secondary data, depending on the research area:
- Quantitative data – data which can be expressed as a number or quantified. These include, for example, the weight and height of a person, the number of hours worked, the volume of sales per month, etc., as well as the weight and length of a person. Quantitative data can easily be manipulated statistically.

We’re talking about qualities. Examples are the colour of the eyes (brown, blue, green), socio-economic status, customer satisfaction, etc.
