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.
- Learning Statistics & Probability using Excel
- Downloadable Excel Workbooks to understand
- Full blown models & simulations in Excel
Recently, I bought a new laptop, because my old Toshiba died down. After installing the OS and other necessary tools (like browser, skype etc.), I have installed Office 2010. Since Excel is my bread and butter, I like to customize it so that I can get more work done. So today,let me share how I […]Continue »
We love to compare. The instinct to compare leaves no one. Even my two year old twins compare their toys with each other (and fight).
It would make Excel hugely popular if Microsoft builds a handy data comparison tool right in to it. Alas, they have customizable ribbon, 3d effects & equation editor…
Since comparison is one of the main uses of Excel, we have written extensively about it here.
But there is always one more interesting comparison problem. Today, I want to share one such problem, based on a comment left by N-Man.Continue »
Count How Many Times a List of Values Occurs in a Range
(or How Can I Simplify My Formula)
Today in Formula Forensics we look at how to count how many times a range of values occurs within a Range of cells and in the process simplify a very nasty formula.Continue »
In the past here at Chandoo.org and at many many other sites, people have asked the question
“How can I display a number multiplied or divided by 10, 100, 1000, 1000000 etc, but still have the cell maintain the original number for use in subsequent calculations”.
Typically the answer has been limited to “It can’t be done” or “it can only be done in multiples of 1000”.
This post will show you how you can display numbers whilst Dividing or Multiplying the cells value by any Power of 10 !Continue »
