Conducting a factorial RCT involves several key steps: 1. Selection of Interventions: Choose the interventions to be tested. These could be pharmaceutical treatments, lifestyle changes, or other preventive measures. 2. Randomization: Randomly assign participants to different groups. In a 2x2 factorial design, for example, there would be four groups: A, B, A+B, and a control group. 3. Implementation: Administer the interventions according to the group assignments. 4. Data Collection: Collect data on relevant outcomes for each group. 5. Analysis: Analyze the data to compare the effects of the interventions, both individually and in combination, using appropriate statistical methods.
