A researcher conducted a factor analysis on a set of 10 variables and obtained the following output for the first two factors:

Factor 1:

• Eigenvalue = 4.5
• Proportion of Variance Explained = 45%
• Cumulative Proportion of Variance Explained = 45%

Factor 2:

• Eigenvalue = 2.1
• Proportion of Variance Explained = 21%
• Cumulative Proportion of Variance Explained = 66%

(a) What is the total proportion of variance explained by all 10 variables in this analysis? (b) What is the communality of the first variable in this analysis?

(c) What is the communalities total of all 10 variables in this analysis?

(d) What is the percentage of variance explained by each variable for the first factor?

(e) What is the factor loading of the second variable on the second factor?
