What should a data science course include? - The Data Scientist

There are many resources, free and paid, for learning data science. However, most of them are not really complete, and they have the wrong focus. The modern data scientist needs to be able to combine various skills, which not many courses take into account. First of all, a complete data scientist needs to know both machine learning and statistics. Also, familiarity with at least either R or Python (ideally both) is a must.
