What are time requirements for courses?

Statistics.com courses typically require about 15 hours per week.

This is an estimate that is based upon a comparison between material covered in a Statistics.com course, in a typical semester-length graduate course in statistics, and in a typical 3-day professional development course. The amount of time you actually spend working in a Statistics.com course can vary widely, depending on your familiarity with the statistical underpinnings of the topic, your own comfort with the topic, and the depth to which you choose to study and explore the topic.

Some course participants focus intently on the topic and are careful to complete all assignments and participate actively in discussion, others are content mainly to observe, picking and choosing the individual parts of the course to which their interest draws them.
