What is the range of correlation coefficients, and how do you know if it is a weak or strong correlation from the coefficient number? 28. Although Galton is best known to psychologists for his work on behavior genctics, statistical methods, and intelligence testing, he also contributed importantly to what other field(s)? 29.

27. The range of correlation coefficients is -1.0 to + 1.0. The strength of the relationship between the variables is considered as strong when the coefficients are close to +1.0 and -1.0. Coefficients closer to 0.0 are considered weak. So a + or - 0.83 is a strong correlation where as a + or - 0.13 is weak correlation.
28. Along with Biology, Psychology and Statistics Galton also contributed the field of Geography. He was the first to create the first weather maps and also established the meteorological theory of anticyclones.
