1. Define the Criteria: Clearly define the criteria for homogeneity based on the objectives of the study. This could be age, gender, socio-economic status, or any other relevant characteristic. 2. Recruit Participants: Identify and recruit participants who meet these criteria. This may involve screening a larger pool of candidates. 3. Verify Homogeneity: Ensure that the selected participants are indeed homogeneous in the characteristics defined. This may involve preliminary testing or validation. 4. Conduct the Study: Once the homogeneous sample is confirmed, proceed with the study as planned.
