For a sample of 1000 employees, several features were observed. Among observed variables are, scores for two psychological tests (PsychTest1 and PsychTest2), years of education (YrsEdu), IQ score (IQ), hours of training (HrsTrn) and hours in a work week (HrsWrk). Following are factor loadings from a factor analysis of the standardized variables. The principal components method was used along with a varimax rotation. Calculate the communality for the variable PsychTest1. Interpret this value.  What is the amount of variance (in the observed variables) explained by factor 1? What proportion of the total variance in six variables is explained by the first factor? Provide a brief interpretation of each factor.
