To calculate RSD, divide the standard deviation of your dataset by the mean, then multiply by 100 to express the result as a percentage. Precision is the backbone of reliable data. Whether you are running complex chemical analysis in a lab, checking quality control on a manufacturing line, or simply trying to analyze the consistency
