How do i get data for my research?

Answer 1

The answer depends on what your research is. You may be able to conduct your own experiments and record the results or you may have to use the results obtained by someone else.

In the first case, you can make sure that the data are exactly what are required for your research, but they may require a lot of expense and effort. Or may not even be possible. For example, I doubt if you can collect your own data for proton-proton collisions at speeds which CERN reaches.

Using secondary data means the information is already there and, if collected and compiled by a reputable organisation, it is cleaned and accompanied by an audit trail. But it may not be exactly what you are looking for and you still may have to pay large sums of money.

Answer 2

Depends on the research. In some cases you do a study or you do interviews or control groups.
