Final answer:
A problem statement indeed covers both the 'why' (purpose) and the 'what' (research questions) of a study or research project.
Step-by-step explanation:
True, a problem statement does indeed address both the 'why' and the 'what' of the research. The 'why' outlines the specific aim or purpose of the study, often highlighting the importance or the context in which the research is being conducted. The 'what' encompasses the central research question or a set of research questions that the study seeks to answer. The problem statement is crucial as it sets out the issues the research is aiming to address and the hypothesis or position (the thesis) which is being tested or explored. Through this, the statement directs the scope and focus of the study and provides a rationale for why this particular research should be carried out. Questions such as the causes, effects, potential solutions, and consequences of inaction pertaining to the problem help refine the problem statement and research questions, ensuring the research is well-defined and relevant.
