I would be glad if I could get an answer different from the answers on the site.

Question: Look for the types of secondary data, and rewatch the accompanying online lecture if you need. Find and add the copies (either electronic or photo or link) of at least two examples of secondary data for each of the seven sub-headings:

1. written materials;
2. non-written materials;
3. area based;
4. time-series based;
5. censuses;
6. continuous and regular surveys;
7. ad hoc surveys.

• Compare and contrast the different examples of secondary data you have found
