Sampling and Sample Size calculation for Medical Research

Sampling in medical research involves selecting a subset of individuals from a larger population to study. The sample size calculation is crucial for determining the number of participants needed to ensure statistical validity and reliable results. Factors such as the desired level of confidence, anticipated effect size, variability, and statistical power are considered to strike a balance between precision and practicality. Adequate sample size enhances the generalizability of findings and supports the robustness of research outcomes, providing a foundation for evidence-based medical practices.
