Mapping Spread of Obesity [Chart Critique and Alternatives]

Mapping Spread of Obesity [Chart Critique and Alternatives]

Over at Flowing Data, Nathan has published an interesting visualization about spread of obesity.

While the above chart is quite interesting, it doesn’t offer much insight in to the data. There are a few drawbacks,

  • Understanding obesity trends for a given state over the years is hard due to the layout and format of the chart.
  • Finding which states are experiencing most obesity growth rates is not possible
  • Ironically, the chart itself is obese. It takes too much space to explain the data.

Nevertheless, the chart looks cool and can be reused with smaller data-sets (quarterly trends or just for a few years). So let’s recreate the same in Excel. While we are at it, let’s also build an alternative visualization to explore the obesity data.

Sara’s Copy Shop – Break even analysis and what-if modeling in Excel [Videos]

Last week, I asked you to share an analysis problem that you couldn’t solve in Excel. We got quite a few very interesting problems in comments and email. In this post, let me explain how to solve Sara’s copy shop problem using Excel.

What is Sara’s copy shop problem?
Thanks to Caroline who posted this problem.

Sara wants to open a copy shop. Each copier costs $5,000 per year to lease. The rent & other fixed costs per month are $300. There is a $0.02 variable cost per copy. Each copier can print up to 100,000 copies per year. She plans to charge $0.11 per copy from her customers. Sara estimates that the demand can be any of the 4 values – 500, 1000, 1500 or 2000 copies per day.

  1. Build a model to estimate profit per given number of copiers & demand values
  2. Find the mix of copiers & demand values that can make maximum profit for Sara (copiers – 1 to 6, demand – 500 to 2000)

Visualizing Financial Metrics – 30 Alternatives

Around 2 months back, I asked you to visualize multiple variable data for 4 companies using Excel.  30 of you responded to the challenge with several interesting and awesome charts, dashboards and reports to visualize the financial metric data. Today, let’s take a look at the contest entries and learn from them.

First a quick note:

I am really sorry for the delay in compiling the results for this contest. Originally I planned to announce them during last week of July. But my move to New Zealand disrupted the workflow. I know the contestants have poured in a lot of time & effort in creating these fabulous workbook and it is unfair on my part. I am sorry and I will manage future contests better.

Analyzing 300,000 calls for help [case study]

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.

Today let’s take up this problem as a case study and understand various methods to solve it.  We are going to learn about writing better lookups, pivot tables, power pivot and optimization. Put on your helmets, cause this is going to be mind blowingly awesome.

Find the seals [Excel puzzle]

First a little back story:

Last Friday (on 29th of July), we (Jo, kids & I) went on a day walk to Red Rocks. It is a rugged coastal walk near Owhiro bay in Wellington. It was a windy & cold day. So why did we brave the elements of nature on this 10km walk? To see seals of course. And we did find a few of them. We also caught glimpses of snowy peaks in Southern Island of New Zealand.

3 Seals Excel Puzzle

Now I can’t take you on the same walk thru internet. There is no Excel function that can teleport you from your office (or home) to Owhiro bay. So I made the next best thing.

An Excel puzzle with 3 hidden seals.

Teach coding to your kids with this maze game [VBA]

My twins (Nishanth & Nakshtra) are now almost 7. They are super keen to learn how computers work. So the other day, I showed them Code.org where there are several coding exercises disguised as games.

  • What is the sum of values that are neither “A” nor “B”?

We can still use SUMIFS, but it will get awfully long. So let’s turn our attention to other functions in Excel.

Yes, I like mangoes.
