I liked the format of this on-line course. The video ”"lectures”" were great. Concise yet thorough. The assignments made a big difference. If I had not done the assignments, I would have left with an incomplete understanding of the subject matter. The fact that Peter also held me to a high standard was important. The mini lectures on various topics using Minitab and Excel, for example, were also very helpful. They saved me a lot time yet pointed me to the right location in the application. I did get stumped on the modules dealing with distributions. It took a couple of weeks (!) to feel comfortable with that subject.
