Answers
Answer:
The advantages of collecting primary data is that you get direct access to real data, its accurate. You will know your ethical approach and you will recognize your biases and eliminate them firsthand to get the best possible research.

Mailing questionnaires is good because its saves time. The respondents can have enough time to read through it properly and answer it.
However, a disadvantage is that they may just answer anything they want without caring about it. They may simply randomly tick off any box.
