What is Scrollytelling?

👋Heya, have you heard of scrollytelling? Is that a typo? Do you mean storytelling? No, I actually mean scrollytelling. I stumbled upon this fascinating concept while exploring the Tableau Extension Gallery, a treasure trove that allows users to enhance the functionality of Tableau by integrating third-party applications. Not only that,

Overview of Tableau BI Tools

Many people think of Tableau as just one product, but it’s actually a suite of tools designed for business intelligence and data visualisation. When I first encountered Tableau, I mistakenly thought it was just a single product: Tableau Desktop. Today, I want to provide you with an overview of

Intro to Customer Segmentation & RFM Analysis

I remember the first time I participated in a segmentation exercise. It involved sending Excel files to sales representatives to categorise their customers into segments A, B, C, and D. The files often came back messy, leading to many back-and-forths with the field teams. It was time-consuming and laborious, and

What is Streamlit?

A couple of years ago, I discovered Streamlit while exploring the field of data science. I noticed some data scientists at my previous employment were using it to build their apps, and it immediately caught my attention as something cool to explore further. Although I made a mental note to

What is Data Virtualisation?

Hi Everyone👋 I've been on a hiatus. I started a new job and have been busy learning the ropes. It's been a while since I felt like a newbie, going from someone who knew most things at work to someone who is learning again. While challenging,

Reflection on My Dashboard Development Journey

I was totally clueless when I first dipped my toes in dashboard development. I thought it was just about making charts, but soon, I discovered it entailed much more. In the beginning, the ride was quite turbulent. I had to learn many things—lots of trial and error, with plenty

Introduction to Exploratory Data Analysis with Seaborn

In my previous blog, I talked about the various data visualisation libraries available in Python, and I highlighted Seaborn as the one I'm focused on learning first. If you haven't checked it out yet, you can find it here: Data Visualization Libraries. Since then, I'

Python Data Visualization Libraries

The two tools I use for data visualisation are Excel and Tableau. They are easy to share with most business users. They have been my go-to tools. But now I want to make a shift. They're not as efficient when exploring data and understanding the data I'

Cohort Analysis- What is it? What do you do with it? How to read it?

My first encounter with Cohort Analysis occurred during a Tableau course I took a few years back. Before that, I had no clue what it was all about. I was blown away by how powerful and insightful it can be. Sadly, I don't get to work on this

Design Thinking Meets Dashboard Development

This blog is a week late- apologies. I spent my last weekend turning around a hefty assignment. The project? I was tasked to assist Daniel, a national marketing manager at Spotify, in navigating through an enormous Excel file with ~ 58,000 data points on Spotify and its competitor, YouTube. Daniel

Data Storytelling

I'll never forget the time I was so terrified of public speaking that I went to my manager with teary eyes because I couldn't deal with the prospect of being the person launching the new BI solution developed by our parent company to over a hundred

Algorithmic Thinking for a Better Life

I remember my first encounter with the term "algorithm." It was in a high school computer science class. At the time, it didn't really make a big impact on me. Fast forward two decades and my perspective has shifted significantly. A big part of this change

Exploratory Data Analysis (EDA) as a Framework to Improve Learning

I never thought I'd go to university, as no one in my family had before me. But in year 11, a teacher changed my trajectory, and I began to believe hard work was key to academic success. Despite all the hours I put in during my undergrad, my

Bias in Machine Learning

Machine learning, part of AI, is everywhere, and there's no denying it's changing the game in a big way. But as much as I'm all for data-driven decisions and the cool things AI can do, I think people need to be aware that it&

Frequentist vs Bayesian Statistics: Understanding the Key Differences

Hi everyone! I'm back from my holiday. Did you miss me? It's been hard to get back into the swing of things, but I think I'll manage. Before I departed for my holiday, many of my blogs have been on exploring statistics. It'

Introduction to Markov Chain

A couple of weeks back, while brushing up on my Monte Carlo Simulation knowledge for the blog post, I stumbled upon the term "Markov Chain" in some YouTube recommendations. Naturally, it piqued my curiosity, so I decided to have a look. Surprisingly, it turned out to be quite

Monte Carlo Simulation-An Overview

During my studies in Applied Finance years ago, I recall sitting in an economics class, slightly disengaged and restless. However, the moment my lecturer announced the topic for the day was "Monte Carlo simulation", my attention snapped back. Oddly enough, it wasn't the financial implications that

Vector Embeddings & Vector Databases for Beginners

I've been delving into the world of databases in preparation for an upcoming project. I'll admit, I'm feeling both anxious and excited, more anxious, I would say, about it. I can sense self-doubt lurking in the shadows and have been actively working to conquer

What is Exponential Distribution?

In my year two days, I think I was seven then, my brother and I always seemed to be the last to be collected from school. Our usual spot was the bench near the entrance, eyes fixed on the gate, waiting for the familiar sight of either mom or dad

What is Poisson Distribution?

When I used to work in a retail pharmacy, I've always been intrigued by the trend in customer arrival before the door shuts. This particular pharmacy I used to work at closes its doors at 8:00 pm every Thursday and is situated in a shopping centre. In

Binomial Distribution Simplified

If you've ever delved into probability distribution through online videos, chances are you've encountered countless coin-flipping examples. They're classic examples, but let's be honest- they are a bit snooze-inducing. My brain thinks it's nap time whenever it sees those coins

What is Normal Distribution?

Last week, I blogged about probability distributions, providing a beginner's view. I finished the blog by asking for a guess of which distribution I would dive into this week. I bet most would have guessed "normal distribution". Am I right? Probability tells me that it'

Probability Distributions for Beginners

If I told my younger self that statistics would become cool one day, I'm pretty sure she would have laughed in my face and said, "Statistic, hip? Yeah, right, what BS," and rolled her eyes. I remember how much I hated statistics when I studied pharmacy;

Bayes' Theorem for Beginners

You know, contrary to what most people might think, math isn't really my strong suit. I've always found it kind of tough because, honestly, it can be pretty abstract and those Greek symbols just add to the confusion. Math's like a puzzle where each

Understanding Instagram Algorithms

"You're not good enough." "What do you have to share with the world?" "People are going to laugh and ridicule you". For years, I allowed voices like these to hold me back. Then, I came across Austin Kleon's book, Show
