The methodology employed by the analyst depends on the nature of the data used. An hypothesis is a specific statement of prediction. Set the criteria for a decision. To do this they complete an experiment.

A hypothesis is an assumption about something. Not all studies have hypotheses. When a proposition is formulated for empirical testing we call it a hypothesis. In hypothesis testing we conduct a study to test whether the null hypothesis is likely to be true.
