A hypothesis is a tentative statement predicting a particular relationship between two or more variables. If you want to know whether or not your study requires a hypothesis‚ ask yourself these questions: Are you undertaking a quantitative study? Does your study take an experimental approach to answer questions? Are you making a prediction about the phenomenon being studied? If your answer to these questions is ’yes’‚ then you will need a hypothesis‚ but if it is ’no’ then you will need a
