A good research question:

• is nonbinary,  more than a simple yes or no, it is a question which offers the opportunity to explore deeper issues and a deeper academic landscape,
• often builds upon research made by others,
• can be supported by data,
• is not too complex or ambiguous
• is neutral. It doesn’t drive toward a  preconceived outcome,
• ….and very importantly, a good research question should hold great interest for the researcher, because it takes a lot of effort and motivation to make it to the finish line!
