Clustering New Addis Ababa 'Sub cities': A Guide for Data Collectors

Thu, 10 Jul 2025 00:00:00 +0000

Introduction

The idea for this project came to me when I was working as a research assistant intern at the East African Trading House plc. We were collecting data from local shops. With population information being scarce, we were told to sample from clusters using the administrative sub-city classifications of Addis Ababa. About 100 samples were going to be taken from each sub-city.

Heads‑up: All the plots below were generated from our survey data analysis using R. For more detail, check out this separate blog post.

🎬 How It All Started

We’re a group of Statistics students who got curious: how much do our classmates really lean on AI tools like ChatGPT? We used this idea as a spring board for our end of year research project. We built a survey, crunched some numbers, and wrote up the results. The data are eye‑opening, the trends are interestingl, and (as we’ll happily admit) the sampling isn’t perfect.

I’ll start this post with a confession. It has been four months since I built the dashboard for The Impostors League project. Spoiler alert: I haven’t opened Looker Studio since then. My memory is fuzzy, but hey—that makes this post more fun to write. Think of it as a reflection, with extra sprinkles of chaos.

What is Looker Studio?

Looker Studio is Google’s free, web-based data viz tool. Think of it as the chill, younger sibling of Power BI or Tableau… the one that doesn’t ask you to install anything or set up a whole environment.

The Impostors League: A Data-Powered Game Night Project

🎮 How It All Started

It began like many fun things do — with friends, games, and a bit of competitive energy. In our dorm, we were deep into football games, especially 2024-modded Pro Evolution Soccer 2017 (PES 17) matches, playing in a mini-league we called The Impostors League. (We refer to ourselves as The Impostors after another one of our favorite games, Among Us.) The banter was there, the competition was present, and then someone said: “Wouldn’t it be cool if we started like a real league?”
