Which step should precede data collection when designing research?

• A. Systematic review of descriptive studies
• B. Single qualitative study
• C. Randomized controlled trial
• D. Meta-analysis

Answer: (B)

Starting with an initial qualitative inquiry helps shape the whole study design before broader data collection. A single qualitative study lets you explore the phenomenon from the participants’ viewpoint, uncovering meanings, context, and potential variables that matter. This grounded understanding informs the research questions, helps you craft appropriate data collection instruments (like interview or focus group guides), and guides sampling decisions to reach information-rich participants. In other words, you gain practical insights into how people experience the issue, which then shapes subsequent data collection to be more focused and relevant. Other options are more about analyzing existing information or conducting the study itself, rather than informing the design upfront. A systematic review or meta-analysis synthesizes previous work rather than generating new, grounded insights to guide instrument and question development. A randomized controlled trial is a type of study that collects data under a specific intervention, not a preliminary step to design. A single qualitative study, used at this early stage, serves as a foundational exploration to ensure the ensuing research collection is well-aligned with real-world perspectives.
