Document Summary
Matrix of correlation: show intercorrelation between the responses of each of these questions. What is the reason for high correlation: really asking about the same thing, some factor shaping these answer in common remove . 00 correlations. Mathematical model of how you would explain the high correlation between the items correlation factors are called factor loadings, how strongly is this measure affect hypothetically by the underlying factor second factor. Non-orthogonal factors: items that are affected by f1 are also present in f2. Orthogonal factors: not related to each other factor analysis doesn"t tell us what these factors are. Naming our first factor looking at the different components to create a name. Does not find real" things: does not discover anything, hypothetical constructs, hypothesized entities not discoveries, you"re not finding anything, assumptions. Does not identify factors: doesn"t tell you what these underlying somethings are.
