Does research objectives have relationship with Hypotheses

Yes, definitely! Research objectives are derived from hypothesis. Designing a research hypothesis is supported by research question.  And a research question arises from the researcher’s interest in a particular topic. Therefore, a research hypothesis is developed before the start of the study and it guides the research objectives. Usually, the primary research objective is coupled with the hypothesis of the study. Furthermore, research objectives define the specific aims of the study and are stated in the introduction of the research protocol.
