Document Summary
Cattell and eysenck: biology over environment; theories based on statistical techniques and genetic factors. Both emphasized scientific discovery and were more interested in biology/genetics rather than developmental events. Correlation coefficient: mathematical expression indicating the extent to which two variables are correlated. Can vary from +1 to -1 (perfect positive or negative correlation) Correlation matrix: display of the many correlation coefficients that result when many sources of information are intercorrelated. Cluster analysis: systematic search of a correlation matrix in order to discover factors. Factor: ability or characteristic that is thought to be responsible for consistent behavior. (cattell"s system: factor also means trait) (eysenck: superfactors= types) Inductive reasoning: method that begins with collection of data, which then leads to hypotheses. Started without a specific guiding hypothesis, collected a large data set, and generated future hypotheses from patterns that emerged from the data.
