This is a follow-up to the last tutorial. Thanks to reddit user /u/small_trunks for noticing my blunder! Unfortunately, 'SUMIFS' couldn't be used on its own to create the dynamic data tables. But don't fret! I have another solution up my sleeve that doesn't rely on volatile functions like 'INDIRECT' and 'OFFSET'! It relies entirely on … Continue reading HOW TO… Excel: A Truly Non-Volatile Solution for Dynamic Data Tables
This is a continuation of the previous tutorial. Due to the volatility of the INDIRECT function, it may be necessary to avoid using it when trying to create large dashboards which will be handling and outputting large amounts of data. So, we’ll need an alternative in these cases. One of the ways this can be … Continue reading HOW TO… Excel: Using SUMIFS to Create a Dynamic Data Table
Creating a full and cohesive user experience in an Excel based dashboard can be really difficult if you don't know where to start. Often, the easiest way to approach the situation will be to utilise Pivot Tables and Pivot Charts, which come with useful tools like slicers to dynamically filter the data with a touch … Continue reading HOW TO… Excel: Create a Dynamic Data Table Using INDIRECT and Combo Boxes

What particularly interested me with … Continue reading How Cryptocurrencies are Shaking Up the World of Big Data
The third and final part of my three part blog series on statistically analysing my performance in the Ketchup vs. Mayo splatfest. Here we use box and whisker plots to look at my performance with the Splattershot.
After watching a long session of ‘VSauce’ videos (great brain food videos, albeit very addictive!), I came across this video discussing ‘Zipf’s Law’. Zipf’s law states that in any corpus of natural language, the frequency of any word is inversely proportional to its rank in the frequency table. This Zipfian distribution applies to many different … Continue reading Zipf’s Law
The second part of my three part blog series on statistically analysing my performance in the Ketchup vs. Mayo splatfest. In this part we look at win/loss ratios on the different weapons used.

After reading some of my other favourite data visualisation blogs (Storytelling with Data to be precise) I came across a new type of visualisation I'd not seen before - the Bullet Chart. Once I saw Bill Dean combine the two-series bar chart into a bullet chart, I couldn't help but think of my last blog … Continue reading Tinkering with Bullet Charts
Spurred on by conversations with my brother and various Reddit posts making claims about immigrant populations in the UK, I decided to check the ONS website to find some of their recent analyses on the UK population (which are fantastic, by the way)1. One claim I remember specifically wanting to check out from a Reddit … Continue reading London Population Analysis
