#### Customer Reviews

##### Very useful

Thank you Dr. McGready. I was not able to understand types of data (NOIR) but this course from iTunes U helped me immensely. I ended up subscribing the entire course! Thank you for sharing the lectures and the worksheets. Another good thing about this course is, it has short lectures (I tend to get bored in long statistics classes).

##### Thanks for the review

Terrific course, reviewed all the sections and finally understand the concepts. Wish section II was available on ITunes. Through the web I am finishing the course. Highly recommend.
