Define 'scope' in research planning.

• A. The funding amount.
• B. The timeline for data collection.
• C. The extent and boundaries of the study—the topics, variables, and time frame included.
• D. The number of researchers involved.

Answer: (C)

Scope in research planning defines the extent and boundaries of the study—the topics, variables, and time frame included. It determines what will be studied and what will be left out, giving the project a clear focus and feasible limits. For example, if you plan to study sleep patterns in urban high school students over one academic year, the scope would specify which sleep-related variables you’ll measure (like duration, bedtime, wake time), the age range, and the urban setting, while excluding unrelated factors like diet or physical activity or rural populations. This clarity guides what data you collect, which questions you ask, and how you design methods, helping prevent scope creep. Financial resources, the data-collection timeline, and the size of the research team matter for how you implement the plan, but they do not define what the study itself is about—that content is set by the scope.
