Ellie Mason

Ellie’s academic background is in geography culminating in a master in meteorology. Like any keen geographer she loves a good map, so naturally gravitates towards spatial data.

She has always been a numbers person, whether that be at her first job analysing weather models for the Met Office or more recently working with customer insights as a market researcher. She loved the analytical part of the roles and was enlightened by the impact data can have for an organisation. However, she felt limited by the more traditional tools used and thought there must be a better way to work with data.

In her spare time Ellie loves cooking, art and travelling, as well as playing tag rugby and running. She has recently completed her first half marathon race!

The Data School is the perfect opportunity for Ellie to bring together her personal love for art and design with the career aspects that have captivated her so far.

DS11 out…for now

The time is here! Today we, DS11, ‘graduate’ and finish the training portion of time at the Data School. The last four months have absolutely flown by. At the mid-point of the training I wrote about the things I’d learnt in the first half, so here I’m going to reflect...

Statistics Series // 3. Classification

This is the final post in my Statistics Series and it will be focusing on classification. Previously in the series I've shown how to generate clusters in both Alteryx and Tableau, as well as describing Time Series analysis and how to do it in Alteryx. Classification...

Tableau Tip: Formatting BANs

BANs, or Big Ass Numbers, are a great way of displaying important figures very quickly. But, often they are not formatted well enough to be effective, or dynamic. They need to really hit the point home. Here I'll talk through 4 quick tips to really make the most of...

Tableau Tip: Splitting the view using Set Actions

Today DS11 learnt about some of the new Set Actions available in the new Tableau 2018.3. As Harry has this topic for his training sessions back in December, he knows them well (see his blog here). Therefore, Harry took us through some of the more ‘common’ examples,...

The infinite usefulness of containers

When I first started using Tableau I found the concept of containers really tricky to get my head, and my mouse around! They seemed confusing and a little unnecessary. I didn’t understand what the difference between a vertical and a horizontal really was, even more so...

Successful Data School Client Projects

During our time at the Data School, we have about 8, week-long client projects. We get the brief and data on a Monday and then have to present our findings on the Friday afternoon. After presenting we then have a feedback session with the coaches and hopefully improve...

Data School Shadow Days

The Data School not only trains us in Tableau and Alteryx, but also give us a chance to develop other skills like presenting, writing and working with clients. In addition to this, in the last month of our DS time ahead of our placements we shadow a member of the...

My Experience of the Tableau Desktop QA Exam

Excitingly, I got to start 2019 as a Tableau Desktop Qualified Associate! I prepped for the exam over Christmas and took it on the morning of New Years Eve. In this post I will take you through how I approached the exam prep, as well as my experience of the exam...

Tableau Tip // Creating YTD metrics on a KPI Dashboard

Using Key Performance Indicators (KPIs) in a dashboard are a great way to give a quick indication of how an organisation is doing. This would be actual number of say sales, or number of people donating to a charity, as well as how these metrics change over time....

2018 Data Reflections

  2018 has been a big year for me, data wise, so I thought it was apt to reflect back before moving forward with some goals into 2019. This seemed especially relevant today, given that I've just passed the Tableau QA Exam! Like my half way through blog, this will...

How to create a Gantt Chart in Tableau

In this post, I'll take you through how to create a Gantt chart. This is a useful chart that shows the duration of events, e.g. delivery times or hospital wait times. The date field is usually on the column, and then the various dimensions are on the rows. I'll be...

DS11 Dashboard Week // Day Five: Boy Bands

The final day of our dashboard week was so fun! We got a cheeky hint from Andy on Thursday evening with a gif featuring the BackStreet Boys.   He then announced, via his blog of course, that we were to analyse data about Boy Bands from the Internet Boy Band...

DS11 Dashboard Week // Day Four: Seattle’s Cyclists

Day four's challenge was back in Tableau - analysing count of cyclists from Seattle's Open Gov data. Over the past four or five years Seattle have implemented counters to track the number of cyclists over time in various parts of the city. This is because there are...

DS11 Dashboard Week // Day Three: Foreign Gifts in Power BI

This morning marks the mid-week day of our dashboard week and I was feeling just about comfortable with the format: understand the data, clean the data, explore and visualise in Tableau. However, Andy threw a curve ball in this morning and one of the rules for day...

DS11 Dashboard Week // Day Two: NOPD Body Wearable Cameras

DS11's dashboard week day two started out well, as the data was relatively clean and could be viewed straight in Tableau. A good deal of my time today was working out what I wanted to say, as well as how. Then it was a 'simple' case of putting it all together in...

DS11 Dashboard Week // Day One: NYC Snowplow

To kick off a wintery dashboard week, the topic of the day was NYC snow-plow (or as we call them, snow-plough) frequency over the last 3 years or so. We were to join this to NYC street level data to explore which streets or boroughs were most often ploughed, as well...

Halfway there….

DS10 graduated on Friday....we (DS11) are now half way through our DS training journey .... and DS12 start tomorrow...time is flying by! I thought I’d take a look back through the first part of my DS journey and take note of five things I’ve learnt so far:  ...
