Research questions are a set of inquiries or probes that researchers use to guide and structure their investigation. These questions help to define the scope, objectives, and focus of the study by providing direction for data collection and analysis. They serve as a roadmap for the research process, helping researchers to identify what they need to know, how they will go about finding out that information, and ultimately, what conclusions can be drawn from their findings. In essence, research questions are essential tools in scientific inquiry, providing structure and direction to guide investigators towards discovering new knowledge or shedding light on a particular topic of interest.
