The eleven DataCamp programming exercises are worth 90% of your grade. They show up as 10 total grades because there are 2 quizzes for Section 1.2. The comprehensive assessments at the end of the course combine to be worth 10% of your grade.
All other components of the course, such as the the discussion boards, are not for credit. Assignments in the course are written in R. R is a flexible programming language designed partly for readability and ease of programming.
Some assignments are on DataCamp and do not require you to install R on your own computer. Verified learners also have access to a comprehensive assessment that requires writing code on a local installation of R.
HarvardX has partnered with a platform called DataCamp External link to create programming assignments that you can do online. There is no need to install anything on your computer. You will be given a set of code to modify and run in your browser. You can take as many attempts as you need on DataCamp problems. When your code works correctly, you will be awarded points. You can also request hints, which will help you out, but hints decrease your point total. Remember that you can always go to the Discussion Board on edX.org for help that doesn’t cost points.
Assignments on the edX platform require you to write code in your own version of R and input the answers on edX. You will have 10 attempts for short answer questions and 2 attempts for multiple choice questions.
