Is the Purpose Clearly Stated?

If research questions or hypotheses are not provided or stated clearly, this suggests the investigation was not well planned. This raises suspicions about the scientific merit of the experiment. The purpose should also be stated in an objective manner. Be suspicious if it appears the author had already decided what the results would be at the beginning of the investigation. This assumption by the investigator could so influence or bias the conduct of the research that the true effects of the experiment may not be identified.
