Principal Components and Factor Analysis
In this course, you will learn how to make decisions in building a factor analysis model – including what model to use, the number of factors to retain, and the rotation method to use.
Overview
Exploratory factor analysis (EFA) is a method of identifying the number and nature of latent variables that explain the variation and covariation in a set of measured variables. In this course you will learn how to make decisions in building an EFA model – including what model to use. You will also learn why principal components analysis (PCA) as a method of factoring can serve different goals. Some prior knowledge of modeling will be helpful.

Learning Outcomes
This course covers the theory of Exploratory Factor Analysis (EFA) and Principal Components and Factor Analysis (PCA). At the conclusion of the course students will understand the differences between EFA and PCA and will be able to specify different forms of factor extraction and rotation.
- Decide which model to use in a given situation
- Decide how many factors to retain
- Decide which rotation method to use
- Describe the difference between exploratory factor analysis and principal components analysis
- Apply EFA and PCA using software
Who Should Take This Course
Market researchers, educational and psychological researchers, sociologists, political scientists, survey researchers.

This program has been a life and work game changer for me. Within 2 weeks of taking this class, I was able to produce far more than I ever had before.
Susan Kamp
The material covered in the Analytics for Data Science Certificate will be indispensable in my work. I can’t wait to take other courses. Great work!
Stephen McAllister
I learned more in the past 6 weeks than I did taking a full semester of statistics in college, and 10 weeks of statistics in graduate school. Seriously.
Amir Aminimanizani
This is the best online course I have ever taken. Very well prepared. Covers a lot of real-life problems. Good job, thank you very much!
Elena Rose
The more courses I take at Statistics.com, the more appreciation I have for the smart approach, quality of instructors, assistants, admin and program. Well done!
Leonardo Nagata
This course greatly benefited me because I am interested in working in AI. It has given me solid foundational knowledge…After completing this last course, I feel I have gained valuable skills that will enhance my employability in Data Science, opening up diverse career opportunities.

Additional Information
Homework
Homework in this course consists of short answer questions to test concepts and guided data analysis problems using software.
In addition to assigned readings, this course also has a discussion forum, the instructor’s expert write-ups on important concepts, and an end of course data modeling project.
Course Text
The course text is Making Sense of Factor Analysis: The Use of Factor Analysis for Instrument Development in Health Care Research by Marjorie A. Pett, Nancy M. Lackey, and John J. Sullivan.
Software
This is a hands-on course and software capable of doing principal components and factor analysis is required; most major general purpose statistical software (SAS, SPSS, Stata, etc.) can do this. The instructor is familiar with SPSS and XLStat.
