Frequently asked questions
What do I need to know about the topic prior to enrolling in the course?
You only need to know basic mathematics. For most people, this is equivalent to basic high school mathematics. You should know concepts like mean, standard deviation, and histograms. This course is also useful for those who already have experience in the subject. In each lecture, recitation, and homework assignment, we use a different dataset and case to illustrate the method. Even if you are familiar with all of the methods taught, you can still learn a lot from the different examples.
What software will be used in the course?
We'll be using two software programs in this class: R and LibreOffice. Both are free online, and you don't need to be familiar with either of them to take the course. R is a free statistical and computing software environment and LibreOffice is similar to MS Office but a free open source program. Specifically we'll use the LibreOffice module, Calc in this course. Don't worry though - we'll teach everything from scratch!
Who can take this course?
Unfortunately, learners from one or more of the following countries or regions will not be able to register for this course: Iran, Cuba and the Crimea region of Ukraine. While edX has sought licenses from the U.S. Office of Foreign Assets Control (OFAC) to offer our courses to learners in these countries and regions, the licenses we have received are not broad enough to allow us to offer this course in all locations. edX truly regrets that U.S. sanctions prevent us from offering all of our courses to everyone, no matter where they live.
