A research question is a specific, focused, and concise query that guides the investigation and helps to identify the problem or issue to be addressed. It should be:
1. _Clear_: Easy to understand and interpret.
2. _Specific_: Well-defined and focused.
3. _Measurable_: Can be answered through data collection and analysis.
4. _Relevant_: Aligns with the research objectives and hypothesis.
5. _Feasible_: Can be answered within the scope of the study.
Research questions can be:
1. _Descriptive_: Seeking to describe a phenomenon or situation.
Example: "What are the demographic characteristics of patients with diabetes?"
2. _Comparative_: Comparing two or more groups or conditions.
Example: "Is there a difference in blood pressure between patients with and without hypertension?"
3. _Causal_: Examining the relationship between variables.
Example: "Does regular exercise reduce the risk of heart disease?"
4. _Exploratory_: Exploring a new area or phenomenon.
Example: "What are the experiences of patients with chronic pain?"
Example of a research question:
"What is the effectiveness of a new medication in reducing symptoms of depression in adults?"
A well-crafted research question serves as a guide for the entire research process, helping to ensure that the study stays focused and on track.
