Mr. Josh Tabor

UPDATE: I am leaving CDO at the end of the 2021-2022 school year to work on my textbooks fulltime. I have really enjoyed my time at CDO as a student and as a teacher. If you need to contact me, please use my gmail address: TaborStats. Thanks!


Welcome to Mr. Tabor's class webpage!  I graduated from CDO in 1991 and have been teaching AP Statistics at CDO since 2007.  Find out more about me by reading the information below.  Find class information by clicking on the Course Information, Course Materials, and Web Resources links to the left.

Defining Moment in Education

When I graduated from high school, I knew I was not going to be a teacher. That all changed during my sophomore year in college when a chapel speaker challenged us to consider our talents and how we can make an impact in the world. I switched my major that semester, became a math teacher two years later, and have never regretted my decision for a second.

Core Educational Belief

“Statistical thinking will one day be as necessary for efficient citizenship as the ability to read and write.” -- H.G. Wells
