Do multivariate situations have you stymied?

Often, you need to measure variables that can’t be directly measured, such as...

  • How do we measure engagement for employees in a particular business unit?

  • How do we measure how desirable a certain geographic area is to live in?

  • How do we measure anxiety levels in military personnel after returning from deployment?

In these scenarios, there is no one measure you can rely on. Instead, you’re going to need to use multiple variables.

And when you’re dealing with multivariate situations, you’re in for a unique challenge.

Fortunately, there are ways to reduce multiple variables into fewer so your data is easier to interpret and analyze. You can do this by using principal component analysis or factor analysis.

But these techniques require many decisions:

  • Which variables matter — and which don’t?

  • How many subscales are you really seeing?

  • How many variables are on each subscale? Which go to which?

Making these choices can be as much art as science… but if you’re not sure of your approach, it can be paralyzing.

Ready to gain confidence in variable reduction?

Learn how in our upcoming workshop: Principal Component and Factor Analysis.

A 4-module online, live interactive workshop starting Tuesday, July 17, 2018. 

I'm Christos Giannoulis, workshop instructor

By the end of this workshop, my goal is for you to understand principal component analysis and factor analysis and all their concepts, steps, and decisions so you can apply them with confidence in your research.

In this four-module live, online workshop, we'll cover:
The theoretical and practical differences between principal component analysis, exploratory factor analysis, and confirmatory factor analysis and when to use each.

The steps and decisions you need to make in PCA and EFA and how to make solid, confident choices about factors to retain, interpretation of loadings, rotation methods, and more.

How to conduct, interpret, and evaluate a CFA.
How these analyses fit into the wider context of scale development and reliability.
Who is this workshop for?
Graduate Students
Research Professionals

This workshop is for you if you:

   -- Need to implement exploratory factor analysis and/or confirmatory factor analysis, and want to ensure you’re conducting and interpreting your analysis well.

   -- Have conducted principal component analysis models in the past with help, and are confused by all the conflicting information you’ve encountered regarding the differences with principal axis factoring analysis. Now, you’d like to understand it once and for all.

   -- Are preparing to defend your dissertation and want to thoroughly understand your PCA, EFA, or CFA so you can answer the questions.

It is NOT for you if you:

   -- Are doing research where each variable is directly measured, and/or your variables are independent.

   -- Rarely encounter multivariate situations where many variables might be highly correlated.

   -- Already run and thoroughly understand principal component analysis and factor analysis, including both exploratory factor analysis and confirmatory factor analysis.

How Does It Work?

This course is a 4-module live, interactive online workshop from July 17 to August 20, 2018.

All sessions are conducted online via live webinar. You can log in via phone or Internet. You’ll see the instructor’s screen to view the presentation…all from your own home or office.

During each webinar session, the instructor will cover core concepts and steps and will leave plenty of time to ask your own questions.

Have more questions? No problem!

In addition to the four webinar sessions, you’ll also meet with your instructor for four additional Q&A sessions where you can get additional assistance on workshop concepts, deepen your knowledge, and clarify any questions.

All 4 Workshop Sessions and 4 Q&A Sessions Are Recorded for Your Convenience.

Where Do I Access Recordings and Material?
For each of the four modules, you will have a set of training resources and material.

As a participant of the Principal Component and Factor Analysis workshop, you can access these for 12-months in our participant-only website, the Workshops Center:
Data Sets
Real research data sets in SPSS, SAS, Stata, and csv formats.
Syntax and Demo Videos
Step-by-step videos to conduct every example in SPSS, SAS, Stata, and R. We give you the code to download so you can save and edit them for your own analysis.
Session slides and supplementary material to support your learning.
Session Recordings
Made available within 48 hours so you can review material at your  preferred schedule.
Exercises + Solutions

About Your Instructor

Hi, I’m Christos Giannoulis, Ph.D., your workshop instructor.

With more than fourteen years of experience as a data scientist, I have extensive experience with advanced exploratory, predictive, and prescriptive analyses using a combination of graphical user interface software (e.g., SPSS modeler, Jmp, Statistica, and Stata) as well as programming languages (e.g., R and Python) on desktop and cloud environments.​​​​​​​

My background in education, statistics, assessment, and evaluation—along with practical experience in applied data science—has given me an excellent foundation in factor analysis. My goal is to support the efficiency and effectiveness of your projects through exceptional statistical analysis and usable results.
Yes, Save My Spot!

So what kind of background in statistics do you need?

This workshop is for researchers, not statisticians. That being said, it is an intermediate level workshop.  

We’re assuming you have solid experience in linear regression and correlation.

If you have questions about whether you’re ready for this class, just email us. We’ll give you our honest opinion. We want you to succeed!

Your Satisfaction Is Guaranteed

As with all our programs, your satisfaction is guaranteed. If you participate fully in a workshop–watch, read, and try out everything included–and find you are not satisfied for any reason, we will give you a full refund, no questions asked. Just notify us within 90 days of purchasing the program.

Yes, I Am Interested!

Q. I haven't taken a statistics course in years. Will I be able to keep up?

As long as you have the suggested prerequisites (solid experience in linear regression and correlation), you should be fine. We know you don’t spend all day, every day, running regression analyses!

However, you WILL need to spend some time each week, both going over the modules, and also “getting your hands dirty” with some data. Expect to spend 2-3 hours per week reviewing the concepts and doing the exercises, and re-running class examples on your own.

And if you have questions during the workshop, make sure to attend the Q&A sessions and/or post on the Workshop Center to clarify anything you’re not clear on.

You know how this goes: The more time you put in, the deeper your understanding.

 Q. What’s your refund policy?

Your registration fee is fully refundable up to 72 hours before your first class session. No refunds will be granted after the program begins.


Q: Do you offer student discounts?

Yes, we do! Current students with a valid ID can register for up to 40% off the standard rate. Click here to receive our student discount on all our workshops: https://www.theanalysisfactor.com/student-discount-list/


Q: Things are very busy at work right now, and I’m afraid I won’t have time to keep up. How much time per week does this really take?

We’ve worked hard to make sure people can take a workshop in the midst of their normal work life. For longer workshops, we build in a week off halfway through the course.

Each workshop webinar session is 1.5 to 2 hours, whether you attend live or listen to the recording.

Afterward, we have a one-hour Q&A session. You don’t have to attend, we just make those available so you can have any questions answered or listen in on others’ questions.

We provide exercises, answers and data sets, so you can practice what you’ve learned each week and get help in the Q&As. These will take you a few hours each week, maybe up to 3 or so. The exercises aren’t required—you’re not graded. But we’ve gotten feedback that they’re very helpful, as it allows you to practice and figure out what you did and didn’t understand.

In other words, each week, there are approximately 2 hours of instruction, one hour of Q&A, and about 2-3 hours of practice time. So if you have a crazy hectic week during the workshop, you have catch up time. But If you have a crazy hectic month, you may be better off waiting as you won’t really have a chance to catch up.

One reminder: You have access to the workshop website, all materials, and a place to ask questions for a year. So if you get behind, you aren’t missing out. You can catch up on your schedule.


Q: I teach/work/sleep during this time and cannot attend live. Is there any way to register and access the webinar sessions later?

Yes! We have participants from many time zones with many different work schedules. In order to support our diverse student base, all modules – including the workshop sessions and Q&As — are recorded and made available to students within 48 hours. They’re screenshot video files, so you’ll hear the instructor talking and see her screen, just as live participants do. You can even submit questions for written answers any time between sessions. Many students take the entire workshop in this manner, never attending a session live.

You can also download and keep these videos forever, so if you need to refresh your memory at any point in the future, it’s yours to review.


Q: I’m outside the U.S. Can I still participate?

Yes. We have participants in our workshops from many different countries. You will want a fast internet connection and either a computer speaker or a telephone if you plan to attend live.


Q: Can I pay with Paypal?

 Yes. When you check out, you can pay directly using our system or paying with Paypal. However, the three-payment option is not available using PayPal.


Q: Can I join the Q&A webinars from my tablet or phone?

Yes. You can join all webinar sessions from your Apple or Android device by downloading a free GoToMeeting app.


Q: This really isn’t a good time for me. Will you be offering this workshop again soon?

We don't have a set schedule for running each workshop. We try to schedule each workshop every 12-18 months, though very popular workshops may be offered more often. We are sometimes unable to re-run a workshop if the instructor becomes unavailable so there are no guarantees that any workshop will be run again.

If you think you'll need the material in the next half-year or so, I would suggest registering now. You’ll get all the materials to download and review at your convenience, and you can attend again for free any time in the next 12 months.

Have additional questions? We’re here to help! Just email us at support@theanalysisfactor.com.
