What is the Role of Sample Size in Different Study Designs?
The importance of sample size can vary depending on the study design: - Randomized Controlled Trials (RCTs): Larger sample sizes improve the balance between treatment and control groups, enhancing the study's validity. - Cohort Studies: A larger sample size can provide more detailed subgroup analyses and increase the study's ability to detect rare outcomes. - Case-Control Studies: Increasing the number of cases and controls can improve the power to detect associations between exposures and outcomes.
