Investigations provide large amounts of information about a wide range of variables

The investigations that provide large amounts of information about a wide range of variales ARE NOT QUANTITATIVE INVESTIGATIONS.

Normally quantitative investigations are focused to a reduced set of variables in order to try to obtain explanations of the independent variable.

On the other hands, qualitative investigations need that the investigator collect a large amount of information about a large range of variables in order to try to elucidate relations about multifactorial facts.
