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 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...

Statistics Series // 2. Time Series Analysis and Forecasting

This is the latest post in my Statistics Series. In the series so far I've shown how to generate clusters in both Alteryx and Tableau and I will now talk about Time Series analysis, Time Series forecasting and how to perform it in Alteryx.   Time Series Analysis and...

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:   Teamwork...

Tableau Tip: Parameter multi-field formatting

When using a parameter in Tableau Desktop or Public, it can be tricky to fix the formatting if a few of the fields within the parameter have different number formats. For example, you may want to use a parameter to allow the user to change between currency, rates and...

Tableau Prep Tip: how to ‘Cross Tab’

Today we spent all day performing data prep. It was really fun, leading to some frustrations and interesting language by both us and the coaches, but ultimately was very satisfying compiling lovely, clean data sets. We used both Alteryx and Tableau Prep, often...

Statistics Series // 1.2 Cluster Analysis in Tableau

Cluster analysis can also be performed in Tableau. This post will show you how, using the same beer data as my previous post which introduces cluster analysis and shows how to perform it in Alteryx.  This is part of a series of blogs I'm writing on Statistical...

Statistics Series // 1.1 Cluster Analysis in Alteryx

Statistics used properly can be a powerful tool to analyse data with so I thought I would do a few blog posts, or a series if you will, on various statistical techniques. First up is Cluster Analysis; primarily explaining in this post how to using Alteryx, but also in...

Data scaffolding in Tableau Prep

Sometimes data analysis is needed for row of data which has no data in. For example, finding out how many people are employed in a certain region on a certain date when all you have is the start and finish date of the employees. This is an ideal chance to use Tableau...

Order of Operations // Sorting within a filter

Sometimes you'll need to sort your data but you've already filtered on a variable, for example wanting to sort/ show the top N products sold within a category/ categories. To do this a parameter, as well as a filter, is needed - but Tableau's Order of Operations makes...

A lesson in Design

Stepping away from our laptops for a day. DS11; Week Three started with a really fun and engaging training day with Caroline Beavon. She talked to us about focusing our design skills, some good visualisation practices and took us through a design exercise with some...

Splitting Fields in Alteryx

As part of the data prep process, you may need to read in a text file, or split a variable into a few new ones. This is because the text file/ variable contains a string of information, separated by a delimiter (e.g. – , / _ ). This will read this as one value and to...

Splitting Fields in Tableau

Sometimes a few of your data fields will be in one column, stored as text with a delimiter (e.g. - , / _ ). Tableau will read this as one value and to have it as more than that you need to tell Tableau to split the field. There are three ways you can do this in...

Tableau chart tips & tricks from Andy’s Zen Master talk

[Spoiler alert - don't read if you're going to Andy's talk at TC18!]   Yesterday, DS11 learnt about Visual Analytics, so it was quite fitting that Andy gave a talk as a Zen Master on 'Tableau Tips & Tricks - Charts Edition'. We got to sit in and watch him create and...

DS11: the first week

With week 2 well underway, I thought it would be a good opportunity to reflect back on our first week as dataschoolers! Whilst I was excited to start DS11, I was also quite nervous! Thankfully that dissipated throughout the week, as everyone was so friendly and made a...

Alteryx Essentials: Multi-Row Formula

The afternoon of Day 2 started with a sort of pre-introduction to Alteryx before the main introduction course of day 3 and 4 of DS11: week 1. As Tableau is part of the Data School interview process we were all fairly familiar with it, but this was the first chance...
