Exploratory Factor Analysis in R
Welcome to the Online Course on “Exploratory Factor Analysis in R”. This is an online course designed to deepen your understanding of how to conduct factor analysis in R. The target audience are graduate students, researchers, and anyone interested in learning how to use open-source data for factor analysis. Factor analysis is a data reduction method used to explore and validate the structure of observed variables in multivariate data.
Please read the course syllabus carefully and email me if you have any questions or need special accommodations.
In this course, you’re expected to read book chapters or papers assigned by the instructor, or provided by your (must be approved by the instructor), watch recorded videos, post questions and assignments, and comment on your colleagues work in the discussion forum. Students are required to use the resources provided by the instructor for this course only and are prohibited from sharing any material provided by the instructor to anyone not enrolled in this course, on social media platforms or any publicly accessible platform, either during or after enrollment without permission from the instructor. Students who violate this rules will be reported to the University’s disciplinary committee for further action.
By the end of this course, students are expected to independently conduct factor analysis in R with open source data or their own data and interpret their findings in according with the APA 7 standards.

Mr. Benjamin Lugu is a third year PhD student and the quantitative research specialist at the Research Assistance Services of the College of Education, The University of Alabama. Benjamin have an MSc in Mathematical Statistics from the African Institute in Mathematical Sciences (AIMS), Rwanda. Benjamin is very passionate about teaching and committed to helping student gain deep understanding of Exploratory factor analysis.
Thursday: 2 – 5pm and Friday: 8 – 2pm
Office hours are strictly by appointment. Meeting can be either virtual or in-person. Please email the instructor to schedule an appointment. Be sure to include the day, date, time and preferred mode of meeting. Please send a follow up email if you do not hear back from me after 24 hours.
Class Meeting Schedule
Admittedly, online classes can be very challenging for some students. To give everyone a good learning experience, a bi-weekly (1-hour) virtual meeting will be held to address all comments and questions. For purposes of compiling register for taking attendance, students are required to register. Please come prepared and with questions.
Meeting schedule will be provided soon

General Course Policy
Late submissions will be accepted with a penalty of minus 1 point for the first day, 2 points for the second day and so forth unless prior permission has been is given Missed assignments will attract a score of zero.
Academic Integrity: Cheating or plagiarism will not be tolerated in this course. You’re permitted to discuss assignments, projects or use AI software like ChatGTP to understand concepts taught in class. However, you are required to write your assignments and interpret findings in your own words, and cite sources where necessary. Students who violate the academic Integrity policy will be reported to the University’s disciplinary committee for further action.
Campus Resource List for Students
College can be a stressful time for students who may often experience issues that get in the way of their academic and personal success and the health and wellbeing of our students is a priority for the University. If you or someone you know is facing a challenging time or dealing with academic or personal stress, anxiety, depression, or other concerns, we strongly encourage and support you to seek assistance or to help friends find the care that they may need by contacting campus Resource List for Students
