Charles Spearman
Charles Spearman was a psychologist. He was born in London, England on September 10, 1863. He died on September 17, 1945.[1] He is known for his work in understanding how people are smart.[2] He also made statistical tests that people still use. One of these is called "Spearman's rank correlation coefficient."[3]
He made a method named "factor analysis".[4] This method helps find patterns in a lot of complex information.
He discovered that if someone is good at one mental task, they are probably good at other mental tasks too. He named this "general intelligence" or "g factor".[5]
