In this first part of a two part course, we’ll walk through the basics of statistical thinking – starting with an interesting question. Then, we’ll learn the correct statistical tool to help answer our question of interest – using R and hands-on Labs. Finally, we’ll learn how to interpret our findings and develop a meaningful conclusion.
This course will consist of:
- Instructional videos for statistical concepts broken down into manageable topics
- Guided questions to help your understanding of the topic
- Weekly tutorial videos for using R Scaffolded learning with Pre-Labs (using R), followed by Labs where we will answer specific questions using real-world datasets
- Weekly wrap-up questions challenging both topic and application knowledge
We will cover basic Descriptive Statistics – learning about visualizing and summarizing data, followed by a “Modeling” investigation where we’ll learn about linear, exponential, and logistic functions. We will learn how to interpret and use those functions with basic Pre-Calculus. These two “units” will set the learner up nicely for the second part of the course: Inferential Statistics with a multiple regression cap.
Both parts of the course are intended to cover the same material as a typical introductory undergraduate statistics course, with an added twist of modeling. This course is also intentionally devised to be sequential, with each new piece building on the previous topics. Once completed, students should feel comfortable using basic statistical techniques to answer their own questions about their own data, using a widely available statistical software package (R).
With these new skills, learners will leave the course with the ability to use basic statistical techniques to answer their own questions about their own data, using a widely available statistical software package (R). Learners from all walks of life can use this course to better understand their data, to make valuable informed decisions.
Join us in learning how to look at the world around us. What are the questions? How can we answer them? And what do those answers tell us about the world we live in?

A course on the macroeconomic accounts, their interrelationships, and the analysis of economic developments.
Is a good, solid argument enough to make an impact? How would you disprove the stance that man-made global warming is just an “opinion”? How would you explain your opinion on school tests, budget cuts, crime, immigration, safety and security issues? No doubt that your persuasiveness relies on your arguments. But your ability to influence and convince critically depends on the way you frame your message.
In today’s world, you often need to reduce a complex reality to a concise and convincing message. Framing is an approach that deals with the way we convey our message: our words, images, and metaphors. To take one basic characteristic, a good frame engages the listeners’ values and emotions – it is easy to remember and it is something that people will usually agree with intuitively.
When you enter into a debate, you might be faced with frames of your opponents – and you will have to reframe the debate. This game of framing and reframing makes the debate to look like a chessboard made out of words. Of course, politicians play this game, trying to pull the debate towards their own words and metaphors in order to win their audience. But the game can be found everywhere: in the world of business, science, media – even at home.
We invite you to join our journey of learning the game of framing and reframing. You will discover how this game is played, and how you can play it yourself.
This course suits people who are engaged with and interested in public and political debates. Not only people from the public sector will find it useful, but also engineers, consultants, managers and anyone who wants to make an impact in discussions and debates.

Learn about one of the greatest engineering efforts in human history: NASA’s Project Apollo and the space race to put a man on the moon.
Apollo 11 landed on the moon in 1969, just eleven years after the first successful satellite launch (Sputnik in 1957) and forty-three years after Robert Goddard’s launch of the world’s first liquid fueled rocket. But the history of rocket development actually can be traced back more than 2,000 years to the experiments of Archytas, an ancient Greek Philosopher.
This aerospace history course will take you back in time and trace the many developments in technology that transformed rockets from celebratory accouterments to weapons and finally to launchpads for human space travel. It is a story of technology, but ultimately the emphasis on this course is about people. Some are very well-known, but others not so.
You will learn how the Chinese introduced rockets as weapons, how early experimenters succeeded through trial and error, how scientific advancement provided the foundation for rocket development and space travel, and how rocket use spread throughout the world prior to the modern era. Finally, you will be introduced to the contributions of rocket pioneers such as Tsiolkovsky, Oberth and Goddard who dreamed of and paved the way for space travel. The course culminates with an introduction of German rocket development in the early 1930s and the emergence the genius rocket engineer Wehner von Braun.
Verified students are eligible to earn Continuing Education Units (CEUs) and Professional Development Hours (PDHs), valid toward continuing education requirements for many professional certifications.
In this course, we’ll trace the evolution of the rocket, from rudimentary battlefield weapon to essential vehicle in the exploration of space.
Beginning with Germany’s effort to avoid the restrictions of the Treaty of Versailles by developing rockets, you will learn how Wernher von Braun led the German effort during WWII. The course will then follow several parallel paths, including simultaneous rocket development in the US and in the Soviet Union, home of another rocket engineering genius, Sergei Korolev.
The end of WWII saw both the US and Soviet Union in a rush to acquire as much rocket technology as possible. You’ll learn how the Cold War between the US and the Soviet Union drove this development and the roles both von Braun and Korolev played in the creation of these advanced rockets.
The course then traces how von Braun and Korolev led the transformation from rockets of war to rockets for space exploration. Von Braun’s and Korolev’s contributions created the space age.
You will learn how Korolev’s R-7, the world’s first intercontinental ballistic missile became the launch vehicle for the world’s first artificial satellite, Sputnik. And you will learn how in the US, now working with Von Braun, used the Redstone ballistic missile to launch their first satellite, called Explorer.
The course culminates with the formation of NASA and America’s official entry it what would soon be called the “Space Race” between the US and the Soviet Union.
How can poor societies become prosperous and overcome obstacles to do so? Professor Sir Paul Collier is one of the world’s leading scholars on this question, and in this economics course you will have the opportunity to learn from him directly.
This course will discuss and examine the following topics:
- The role of government and the key political, social and economic processes that affect development;
- Why societies need polities that are both centralised and inclusive, and the process by which these polities develop;
- The social factors that are necessary for development, including the importance of identities, norms, and narratives;
- The impact of economic processes on development, including discussion about how government policies can either promote or inhibit the exploitation of scale and specialisation;
- The external conditions for development, including trade flows, capital flows, labour flows and international rules for governance.
Enrol in this course to understand the factors that influence economic development and the different development paths that countries across the world have taken.
