I'm not sure what review title and review text mean. The teacher is as clear as anyone could possibly be! He is extraordinary. The concepts are described SO clearly, the slides are perfect, and the whole online format is super user-friendly. I learned SOOOOOO much in this course and enjoyed every second of it because it was so well done. Pedagogically, it's superior to any course online or in person I've ever taken. (And, I've have a Ph.D., so I've taken LOTS of course.) I took issue with a few quiz questions because on two or three occasions the material we were quizzed on were not in the learning materials. For example, there was a question that referred to Type I and Type 2 errors in control charts and that topic is covered in the Green course, not this one. Also there is one question that I absolutely do not understand and wish I did. I don't believe it was explained in the lesson. It is: The percent of outcomes that would be expected to occur plus or minus two standard deviations from the mean would be ______________. The answer is 5%. I do not get that at all. Anyway! Thank you. It was excellent. I did the greenbelt first, but decided that in order to be super solid in my understanding, it may be helpful to start from the beginning. And, it was. I will do the Blackbelt next.
