WebFeb 3, 2011 · In addition to the factor score matrix seen in Table 2, SPSS creates a factor matrix that includes all extracted factors from a factor analysis (see Table 3). The entries in Table 3 are an indication of how useful each factor is for explaining the variance of the measured variables; but do not be misled: They ARE NOT FACTOR SCORES! WebThis process is used to identify latent variables or constructs. The purpose of factor analysis is to reduce many individual items into a fewer number of dimensions. Factor analysis can be used to simplify data, such as reducing the number of variables in regression models. Most often, factors are rotated after extraction. prolink router unlock
