A research design provides an overall plan that connects research questions with methods of data collection and analysis. It specifies the type of study, sampling strategy, tools, timing and procedures to be used. By planning these elements coherently, the design enhances internal validity and feasibility, ensuring that the study can meaningfully address its questions. Therefore it is often called a blueprint of research.
Option A:
Option A suggests random decisions, which contradict the idea of design as planned and systematic. Randomness at the planning stage can lead to weak or invalid studies.
Option B:
Option B correctly highlights that design is a logical plan linking questions, data and analysis. It underlines the purpose of design as providing structure and direction to the study before implementation begins.
Option C:
Option C confuses design with bibliography. References are important but are not a plan of procedures.
Option D:
Option D refers to raw data, which are outcomes of research activities, not the plan that precedes them.
