Despite enjoying 5 years of studying Biomedical Engineering, Hanna got fed up with the theoretical point of view common in academia. After being introduced to Tableau during workshops with Luke, she decided to dig deeper into data visualisation and data science. It was refreshing to find something that was focused on data but also allowed to be creative. Within the first week, Hanna got hooked on Tableau and Alteryx and was convinced the DS was the right move.

Tableau (Server) Tip: Intro to User Filters
Even though we might be finishing the training, it doesn’t mean the learning is
finished. Earlier this week we had a Tableau Server Refresher with Ravi. We went
over some topics we wanted clarified but also discussed user filters which we
hadn’t had much experience with so far

How to Start with Alteryx Designer
A few people have asked me how to start their journey with Alteryx and so I
decided to write down what I know so it’s easier to pass the information.
First of all, there are a few different products that Alteryx

16 practical tips on project management
Client projects are quite a big part of the Data School training. It’s a
week-long engagement during which one member of the cohort is the project
manager and the rest is actually working on the client’s requirements.
Two weeks ago, it was my turn to be the project lead

Dashboard Week Day 1: The Fun Begins
If you don’t know what a dashboard week is, check out Andy’s post

supposed to prepare the data, make a viz and write a blog before 5pm.

is a bit of an overstatement

Teaching Tableau
As you may (or may not) know, one of the tasks that data
schoolers are exposed to is teaching others. I have done it a few times now in
different settings and thought I’d share my observations for the benefit of
future cohorts and those who are just interested

Scheduling Alteryx workflow that updates data used in Tableau
This is something with a lot of potential. Let’s say you are gathering your own
data (eg. via web scraping or APIs) and you want your visualisations to be
up-to-date without the need of you running the data workflow manually

Tableau Tip: Tooltip Viz
I was always impressed whenever someone had an actual chart/view whatever you

detail for those interested without cluttering the dashboard. After one of the
Friday projects, one of our coaches, Carl [https://www

Week 1 done, 15 more to go
You’d think the title is about the training part of Data School. Wrong. This
post is about something that resulted from what we’ve learnt this week (Alteryx)
and what I’ll refer to as the Alteryx Challenge.
Often the first week of a new job or uni is rather relaxed and sometimes even
boring
