Michael Louis Friendly (born 1945) is an American-Canadianpsychologist, Professor ofPsychology atYork University in Ontario, Canada, and director of its Statistical Consulting Service, especially known for his contributions to graphical methods for categorical and multivariate data, and on the history ofdata andinformation visualisation.[1][2]
Born inNew York City, Friendly obtained his BS in 1966 from theRensselaer Polytechnic Institute, and his MS in 1969 fromPrinceton University. In 1971/2 he also obtained his PhD in psychology at Princeton under supervision ofHarold Gulliksen and Peter Ornstein, with the thesis titled "Proximity Analysis and the Structure of Organization in Free Recall."[3][4]
Friendly's first research project in the field ofpsychometrics andcognitive psychology had started at theEducational Testing Service andPrinceton University, and was made possible by a Psychometric Fellowship awarded by the Educational Testing Service. After graduation Friendly jointed the Department of Psychology at theYork University in Ontario, Canada, where he continued his research. At the York University he was appointed Associate Professor and later on Professor of Psychology, and since 1985 also director of its Statistical Consulting Service.
Friendly's research interests have developed over years. It started in the 1970s with the application of quantitative and computer methods to problems incognitive psychology, including the cognitive aspects of extracting information from graphical displays.[6] In the 1990s Friendly started focussing on the history of statistics and data visualization, and furthermore graphical methods for data and information visualization.[7]
