What is an experimental design diagram?

An experimental design diagram is a visual representation of the research design, showing the relationships among the variables, conditions, and participants. It helps researchers to:

  1. Clarify the research question and hypotheses
  2. Identify the independent, dependent, and control variables
  3. Determine the experimental conditions and treatment levels
  4. Plan the sampling and data collection procedures
  5. Visualize the flow of participants through the study
