In biomedical research, confusing standard deviation (SD) and confidence intervals (CI) is a common pitfall. Do you know the difference? One describes the spread of your sample data, while the other estimates the precision of a finding for the entire population. This guide breaks down the essential distinction, showing you how to use SD to describe your sample and CIs to infer your results, ensuring your data analysis is precise and powerful.
