Answer and Explanation:
1. A research study requires that a research hypothesis be developed right at the beginning of the research project, even before the experiment is established. This is because the experiment will test the hypothesis and therefore, it must be formulated beforehand.
2. The terms used in the research must be defined in a simple, objective and formal way, avoiding language addictions, repetition of definition and use of the expression "is".
3. These terms must be related to the subject that the research is related to, as the research was not mentioned in the question it is not possible to point them out, but the terms must be those that are not common and need to be explained to the research reader.
