• It is too broad and vague

• It is unrelated to existing literature

• It is feasible and manageable

What does a well-defined research problem help you establish?

• A specific research methodology

What is the primary purpose of a research hypothesis?

• To summarize the research findings

• To provide background information

• To guide the research and make predictions

Which of the following best describes a research question?

• A statement that presents a proposed explanation for a phenomenon

• A specific, focused query that the research seeks to answer

• An outcome predicted before the research is conducted

• A summary of the research findings

When is a research hypothesis typically used?

• At the beginning of the research process to guide investigation

• After data collection and analysis to summarize findings

• When no research question is available

• Only in qualitative research studies

What does a research hypothesis provide that a research question might not?

• A clear methodology for data collection

• A statistical analysis of results

What is a sampling frame?

• A list of all possible elements in a population

• A statistical tool for analyzing data
