there are lots of cases the place researchers can perform exploration using a blend of both of those qualitative and quantitative approaches.

Ratio Scale: The ratio scale is easily the most Sophisticated measurement scale, which has variables which are labeled if you want and Have a very calculated distinction between variables. Besides what interval scale orders, this scale has a set place to begin, i.e., the particular zero price is present.
