Analyzing 300,000 calls for help [case study]
Over the weekend, I got an email from Mr. E, one of my students. Mr. E works at a police department in California and as part of his work, he was looking at calls received by police. Whenever police get a call for help, multiple teams can respond to the call and go to the location. All of these dispatches are recorded. So a single call can have several such dispatches. And Mr. E wanted to findout which team responded the first. The problem?
Finding the first responded team is tricky.

Doing Cost Benefit Analysis in Excel – a case study
Imagine you are the in-charge of finance department at Hogwarts. So one fine day, while you are practicing the spells, Dumbledore walks in to your office and says, “Our electricity bills are way too high. As the muggles don’t accept wizard money, we have to find a way to reduce our power consumption.”
So you summoned the previous 12 month utility bills to examine energy consumption patterns, and pretty soon you realized that most of the electricity consumption is due to the light bulbs. You suddenly have a brilliant idea. Why not replace the light bulbs with a variety that consumes low power? A light bulb moment indeed.
Your next step is to figure out what varieties of light bulbs are out there. Fortunately this is easier than catching a snitch in a game of quidditch. A quick search revealed that there are 3 types of light bulbs:
- Regular incandescent bulbs (the kind Hogwarts currently uses)
- Compact Fluorescent Light bulbs (CFL)
- Light Emitting Diode bulbs (LED)
Now your job is to do a cost benefit analysis of these options and pick one.Continue »
