Jonathan Waerner
Jonathan graduated from the University of Wollongong with a Bachelor’s in Mathematics. When looking for graduate positions but not quite ready to stop learning, he thought the Data School was too good to be true. Jonathan’s passion for data sparked discovering vlookup and is excited to find this is just the tip of the iceberg! Outside of work, Jonathan enjoys playing soccer, cooking up a storm, and spending time with his family and friends.
Dashboard Week, Day 4 – Gapminder Data, Visualizing Life Expectancy
Today we focused on using Data-sets available from Gapminder. These Data Sets cover a huge range of global measures, and it was awesome to explore them! I was especially excited to see many data-sets that covered many countries and went back so far in time (some back...
Dashboard Week, Day 3 – ICC Cricket World Cup Data
Today we worked on making dashboards using the cricket data Craig has been working on recently. I thought I’d use this opportunity to make a dashboard showcasing some radar charts. I have been meaning to write a blog on these charts for a while, I think they are great...
Dashboard Week, Day 2 – Coffee Pods and Plastic Waste
Today we were given a much cleaner set of tables, but were challenged instead by being restricted to using Power BI. Since we have only done an introductory session on Power BI, I feel like this was a “thrown in the deep end” type of challenge. It’s also a great way...
Dashboard Week, Day 1 – Domain API
The first day of Dashboard Week kicked off with an API challenge. We were all required to connect to the Domain API, which gave us data for property listings and agents. I decided my Dashboard should focus on giving the user a way to explore many properties at once...
Learning to Code – Starting from Scratch
Both Tableau and Alteryx provide a great visual user interface and provide complex outcomes with simple drag and drop actions, meaning that people from all backgrounds can try their skills at Data Analysis. However, they still occasionally require typed commands. This...
Quick Table Calcs, how to use, how to understand
A few weeks ago, we learned how to use quick table calcs in Tableau, this feature allows a user to quickly explore their measures and dimensions in a different way, or to quickly apply a commonly used calculation to your selected measure. They are fantastic for...
Grouping With Tableau Prep Builder
This Blog I will be writing about a feature of Tableau Prep Builder that I really like using, “Grouping”. I’ve grown to appreciate how it is done in Prep Builder after getting frustrated using other methods. To clarify, grouping is collecting values of a dimension...
Exploring Crime Data with a Tableau Dashboard
One of my favorite things about Alteryx is its allows us to automate a repetitive process very easily. This blog takes you through a data set that I otherwise would not have been able to generate in a reasonable time frame. Prior to Tableau, I don't think I would have...
My Brain Workout: Gym locator using API’s and Spatial Tools
This week I decided my spare time should focus on revising Spatial Tools in Alteryx and using API’s. Up until this point, I had only successfully retrieved data from one API (cheers Zomato). Along the way, I have been unsuccessful with a few others, so I was...
Don’t Regret Regression
Week 2 of the Data School gave us a closer look at all things Tableau. One thing we covered was Regression and Forecasting, in the analytics tab. One thing I remember from my Stat classes in uni, was to be careful when using regression, as it is not always a valid...
