We will use the psych package in R, which is a package for personality, psychometric, and psychological research. It consists of a data set—the bfi data set—which represents 25 personality items with three additional demographics for 2,800 data points. The columns are already classified into five factors; their names start with letters A (agreeableness), C (conscientiousness), E (extraversion), N (neuroticism), and O (openness).

Run a factor solution with four and five factors and see which one fits the data better.

Provide the relevant R code and interpret the output.

 

Q2. Which command is used to create factor scores?
