Charles Spearman

Charles Spearman (born 1863, September 10th - died 1945, September 17th) was a psychologist. He was British, born in London, England.

He is known for his work in understanding how people are smart.[1] This is another word for intelligence. He made statistical tests that people still use. One of these is called the Spearman's rank correlation coefficient.[2] He did this to help people. It helped the field of psychology. Psychologists are a type of doctor (not a medical doctor).

Charles Spearman made a method named factor analysis.[3] This method helps find patterns in a lot of complex information. Psychology is the study of the mind (mentally). He discovered that if someone is good at one mental task (such as mental calculation or mental maths), they are probably good at other mental tasks too. He named this general intelligence factor (g factor).[4]

He died on September 17, 1945.[5]
