Abstract
Sir Francis Galton in Great Britain was interested in studying individual differences based on the work of his cousin, Charles Darwin. In 1869, Sir Francis Galton demonstrated that the mathematics scores of students at Cambridge University and the admissions exam scores at the Royal Military College were normally distributed. In 1889, Francis Galton published an essay suggesting the idea for examining how two traits varied together (covaried). This effort resulted in the first use of the term “regression.” Karl Pearson in 1898, based on the suggestions made by Sir Francis Galton, investigated the development of a statistical formula that would capture the relationship between two variables.
