How is variation related to measurement? - Answers

Variation refers to the differences observed in data or measurements due to inherent differences in the subjects being measured or the measurement process itself. It highlights the spread or diversity within a dataset, which is essential for understanding the reliability and accuracy of measurements. By analyzing variation, researchers can identify patterns, control for errors, and improve measurement techniques, ultimately enhancing the validity of their conclusions. Thus, understanding variation is crucial for interpreting measurement results effectively.
