R. G. Pearson

R. G. Pearson was a renowned American biochemist known for developing the Pearson correlation coefficient, a statistical measure that assesses the strength and direction of a linear relationship between two variables. This coefficient ranges from -1 to +1, where +1 indicates a perfect positive correlation, -1 a perfect negative correlation, and 0 no correlation. Pearson's work helps researchers determine whether and how strongly two variables are related, which is fundamental in fields like biology, social sciences, and data analysis. His contributions provided a vital tool for understanding associations in scientific research.
