Karl Pearson Quotes

Statistician
England
1857

Karl Pearson (1857-1936) was a British mathematician, statistician, and sociologist who is best known for his contributions to the field of statistics. He developed the Pearson product-moment correlation coefficient, which is used to measure the strength of the linear relationship between two variables, and the chi-squared test, which is used to test the goodness of fit of a model to observed data. He also founded the world’s first university statistics department at University College London and was the first editor of Biometrika, a journal devoted to the application of statistics to biology. He wrote several influential books, including The Grammar of Science (1892) and The Ethic of Freethought (1909).Read Less

In 1892, Pearson founded the journal “Biometrika,” which became a leading publication in the field of statistics.
He also established the Biometric Laboratory at University College London, which became a center for statistical research and training.
In 1901, Pearson was appointed as the first Galton Professor of Eugenics at University College London, where he conducted research on the hereditary nature of intelligence and physical characteristics.
He was a founding member of the Royal Statistical Society and served as its president from 1913 to 1915.
Pearson was also a member of the Royal Society and was awarded its prestigious Copley Medal in 1924 for his contributions to statistics and biometry.

Key Contributions by Karl Pearson

Pearson is best known for developing the Pearson correlation coefficient, which measures the strength of the linear relationship between two variables.
He also developed the chi-square test, a statistical method used to determine the significance of the relationship between two categorical variables.
Pearson’s work on the theory of errors and the method of moments greatly influenced the development of modern statistical theory.
He made significant contributions to the field of biometry, particularly in the study of heredity and evolution.
Pearson also played a crucial role in the development of the field of eugenics, which aimed to improve the human race through selective breeding.
