One of the best teachers I've ever had. YOU DON'T NEED TO BUY A BOOK (I wish I hadn't)because his notes are so clear and you don't have any homework from the book. The only reason you would need the book is if you need the tables in it because you don't have a TI-83plus. HIGHLY RECOMMEND A TI-83plus! Makes an easy class all the more easier.

Sullivan is the best statistics teacher at Sierra College. Highly recommend buying a TI-83 Calculator because his lecture notes are hands on using the TI-83 (Buy TI-84 Plus for a section in stats that the TI-83 can't do). He makes STATS a piece of cake. No HW (only for clarity). 4 Exams 90% & Group Project 10% of your grade. SIGN UP EARLY & FAST!!!

I took Prof. Sullivan Fall 2015 online. He was quick to respond to any questions . I must add his lectures are EXCEPTIONAL! I love that they are a video, as I am a visual learning and you can following along if you print or buy the notes to follow. His quizzes are exactly what you learned in lecture. I wish he taught other math courses. Sigh**

Fabulous instructor. Thorough instructions on process and detailed instructions on how to enter information into the calculator. Took this class online and although it took time to go through lectures, exercises and reviews it all paid off when it was time to take the tests. I highly recommend this instructor for statistics.
