In this blog I share techniques on how to convert a dataset containing words into actual numbers (integer or float) save the output with numbers to an external CSV/XLSX data file. If you’re wondering why would one ever need this? Here’s a scenario: A list of movies and their corresponding revenues were read into a […]

Eiesenhower Matrix in Excel (Quadrant Matrix)
Former US President Eisenhower is known to have said: “What is important is seldom urgent and what is urgent is seldom important.” This is reflected in a popular quadrant design, often referred to as “The Eisenhower Matrix”, used to effectively prioritize tasks according to their urgency and importance. This can be expressed in a quadrant matrix (image) […]
HOW TO CREATE AN ORGANIZATIONAL CHART FROM EXCEL DATA
If you’ve worked with Visio or PowerPoint, you may have used their built-in organizational charts…and manually enter the information for each node. But what if you have the data already as a table, as in a CSV or Excel file? You can use that data and create an organizaitonal chart right within Excel. However, you’ll […]
Venn Diagrams Done Right (Excel)

While they are ubiquitous, very few diagrams actually update automatically when data changes…that’s because most of them are one-time illustrations with no ties to the underlying data…they’re just drawn up like Infographics. It doesn’t have to be that way! In this […]

BACTERIAL GROWTH SIMULATION (Binary Fission)
Here, I present a quick simulation application (runs in the browser) of population growth of bacteria that mutiplies following binary fission reproduction. Basically, it’s the division of a single cell into two or more cell and the regeneration of those parts to separate cells resembling the original. To play the simulation, just navigate to the […]
Did your promotion work?
In an earlier blog How Well Are Your Incentives Working? I shared methods on how to calculate the various chances of success based on some campaign data (e.g. new sign-ups for membership) from various trials using Binomial distribution. In this post, I show how to determine if events occurred due to random chance or affected […]
Waffle Charts (3 methods + bonus)
You may heard of “waffle” charts. They’re usually depicted with little blocks in a larger area to give an easy view of proportions. The idea is not any different from a pie chart, or an area chart, or even a treemap…it all depends on your audience and preference. However, it’s suitable for small number of […]
