Q

When is research valid?

A
  • Research is valid if it provides a true picture of what is really “out there” in the world.
  • The more in depth the research, the fuller picture we get of the thoughts and feelings of the individuals acting, so more valid the data.

Q

In which type of data will validity lack in?

A

In more quantitative research, such as social surveys, validity may be lacking because the researcher has decided on what questions should be answered by respondents, rather than letting the respondents decide on what they want to say for themselves, as it typically the case with more qualitative methods.
