Is there a best practices guideline for when to use qualitative

This answer was rated:

Is there a best practices guideline for when to use qualitative research vs quantitative? Not a definition of what each of these comprise but more of a check list to go through to decide which is a better method for a given project?
Hello and welcome.

Personally i use quantitative when i want to see a direction or a trend from the data. I use qualitative when i want to understand the data to a deep level. So the quantitative give me theories ideas while the qualitative help me to validate/invalidate those theories.

You also have to consider the cost. Depending on the type of research, usually quantitative cost more (not always the case).

Are there any published articles that explain the same? Maybe like a list of questions one can go thru to decide?

You can use that document:

I am not in accord with many points in this, but that is part of what a tool is. You can use a tool the way you want. In fact you can do a qualitative AND quantitative study at the same time.
