Formula Forensics 018. Retrieving the Nth number from a Range which has Gaps.
Over Easter, while we were all busy eating our Easter Eggs, at the Chandoo.org/Forums, Slk213 was worried about how to retrieve the Nth number from a row of data which had gaps in it.
Today in Formula Forensics we will look at how to solve this problem.

Learn Statistics & Probability using MS Excel
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.

It is no exaggeration that knowing excel formulas can give you a career boost. From someone starting at the long list of numbers, you can suddenly become a data god who can lookup, manipulate and analyze any spreadsheet.

Here is the complete list of entries for the twitter formula contest.
Formula 1 Style Sorting of Times (Durations) in Excel
The other day I was watching Formula 1 on TV. I think it is the ideal game to follow for a lazy dude like me. It is on every other weekend. It takes .32 seconds to understand the game and 3.2 seconds to know the points and scoring mechanism. But I am not here to convince you to follow the game. While looking at score boards, it struck me,
“how about writing excel formulas for sorting a list of durations (or numbers) in the formula 1 order?”
How to Round and Sort Data using Excel Formulas?
Cheryl asks via e-mail, “I was wondering if you could help me figure out how to combine the round formula with the rank formula? I need to first round all the numbers and then rank them.”
