What PCA is & Why You Should Master It

Principal Component Analysis (PCA) is a powerful statistical technique used for dimensionality reduction in data sets. By transforming a large set of variables into a smaller one that still contains most of the information from the large set, PCA helps simplifying the complexity in high-dimensional data.

This course is ideal for anyone looking to increase their skills in data analysis, machine learning, or data science. PCA not only enhances data visualization but also improves the efficiency of predictive models by reducing overfitting. Mastering PCA opens up a deeper understanding of your data, enabling you to uncover hidden patterns and make more informed decisions.

While a basic understanding of statistics and R programming is helpful, it is definitely not required for participation in this course. We begin with the basics, ensuring a solid foundation, before progressing to more advanced topics in a structured and comprehensible manner.


This course guides you through the essentials of reducing data dimensionality, step-by-step.

  • Even if… you’re stepping into PCA with no prior experience.
  • Even if… you’re familiar with basic statistics, but PCA seems like a big leap.
  • Even if… you’re a beginner in R and feel overwhelmed by PCA syntax.
  • Even if… you’ve thought to yourself “applying PCA in R is too complicated for me”.

Meet Your Instructor: Joachim Schork

R Course Instructor

Hey, I’m Joachim Schork and back in the days, when I started my journey as a programmer and statistician, applying statistical methodology in R programming felt like an impossible challenge to me.

After finishing my bachelor’s degree in Educational Science, I decided to focus more on programming and statistics, but when I started my master’s in survey statistics, I felt hopeless. Do you know that moment when you scream at your PC screen after several hours of unsuccessful coding attempts?

Since the start of my educational journey, I have used online resources to complement the university’s official learning materials. This has helped me a lot, but at the same time I felt like I was often spending too much time on a video or blog article because many of these resources don’t get straight to the point.

This was one of the reasons why I founded Statistics Globe more than five years ago. Meanwhile, I had completed my master’s degree, got my first job at a national statistical institute in Europe, and was rewarded with an EMOS certificate that approves special knowledge in the field of official statistics. I had gained extensive knowledge in the area that I wanted to pass on.


However, I didn’t want to create endless tutorials that didn’t fulfill the need of its users. Instead, I created straightforward content designed to guide users to solutions for their problems as quickly as possible.

Now, five years later, Statistics Globe has gained:


20 million clicks
on the website

Statistics Globe Website Clicks


3 million clicks
on YouTube videos

Statistics Globe YouTube Channel Clicks


50 thousand followers
across Social Media platforms


This is such an incredible success, and I’m so thankful to everybody who participated in this journey! And please don’t get me wrong: I don’t want to brag about these numbers, but I think they can show you that my content works.

With this online course, I’ve combined all of this experience and knowledge into a single resource on how to use the R programming language to apply PCA – one of the most popular methods in statistics and machine learning.

However, the aim of this course extends beyond understanding how to apply this method; it’s also about enriching your data science skill set in general.

  • Dear Prof Joachim;
    Science R, especially PCA is used by many research scholars, university lecturers, MSc, Ph.D., and Post-doc students. I am a part of these. I have used a few but I want to get to know it more thoroughly and am keen to use it in the future as well. However, the payment terms may not be suitable for me. So I would kindly and lovingly ask you to provide us with a direction that I can follow for free. Thank you very much for your invaluable effort and time for consideration.
    Best regards!

    • Hey Gemechu,

      Thank you very much for your kind comment and your interest in the course. I understand your situation, but unfortunately, I’m not able to give away the course for a cheaper price. It takes me a lot of time to develop and run the course, and I cannot do that without a compensation. I hope you understand! However, you can still watch all the videos on my YouTube channel for free. You will also find some PCA videos there.

      All the best,

  • Ok

  • Hello!

  • Any student discounts

  • Good evening, I am trying to switch career into Business Intelligence Analyst or Business Data Analyst, or related. I have been taking courses on R, data visualization, Python, but still I feel I have basic knowledge on these subjects. I already have degrees BS in Business and Finance, MBA in Accounting. As I do my search for these positions, I see that R and Data analysis and Python skills are required for these position. I do not see Principal Component Analysis (PCA) as one of the requirements but overall R is a requirement. Is this a good course to take in my pursuit interest ? second if you can recommend a python courses that can help me to take my Python skills from basics to mid level and get stronger with Python skills it would be great.

    • Hi David,

      Thanks for sharing your background and your interest in the course. PCA is a technique that is applied in many different fields, such as Finance, Consumer Behavior, Neuroscience, Genomics, Climatology, and so on. I think it would be a nice addition to your skill set as well. Furthermore, you will improve your general R programming and statistics skills by doing this course.

      However, if you’re seeking a course that focuses only on the basics of R or Python, this course may not be the ideal choice for you right now. You can find a free introduction to R video on my YouTube channel. I don’t have such a general video on Python yet, but maybe this introduction to DataFrame manipulation using pandas in Python helps.

      All the best for your learning progress!
