One of the most dreaded courses during my under-graduation is Probability, Statistics & Queuing Theory. We called it PSQT. I struggled to understand the significance and concept of this course as I could barely concentrate in the class. We had a professor, who is probably a genius, but the moment he started the class, I would magically fall in to one of my after-noon naps. When I woke up, we are either in the middle of an elaborate t-test or going thru intricacies of a Markovian queue.

This was all 11 years ago. Later in life, I have embraced the world of probability & statistics. I still fear queues. May be I will get there one day. 😉

A good understanding of statistics & probability theory is necessary if you want to model complex real-life problems using Excel or similar tools. Naturally, Excel has several functions, features & supported add-ins to help you in this area.

Today, I want to share some of this with you. This article is broken down in to 3 parts.

1. Learning Statistics & Probability using Excel
2. Downloadable Excel Workbooks to understand
3. Full blown models & simulations in Excel
