In this second episode, Rob and Stephen explore what data science is and its role in the charity sector with Wood for Trees Data Scientist, Kate Houghtaling.
Kate hails from New York State, where she studied Mathematics as an undergraduate at Hamilton College. After enjoying interning at her college, working with spreadsheet data, she wanted to move into more applied and technical maths, which led her to complete a Masters degree in Data Science at the University of Bath. And, luckily for us, she’s been working at Wood for Trees ever since!
Kate believes data science is the culmination of bringing together maths, statistics, computer science and domain knowledge. But contrary to how some may perceive data science, it doesn’t have to be complicated. Day-to-day, it’s working with datasets, problem solving and making future predictions based on data. The tools used may be advanced but more simple tools have a place too and you can even use pen on paper for some elements of data science. It can sound a lot more fancy than it is!
So, where does the role of a Data Analyst end and that of a Data Scientist begin? At Wood for Trees, it comes down to task allocation and what expertise may be best applied but there’s much cross-over. For example, the Python coding language is used in statistics and machine learning, and Tableau and Power BI are used in analysis. It’s all about picking the most appropriate tool and skillset for the job. One core difference is that data analysis is descriptive and historical whereas data science looks at forecasting and the future.
What’s important isn’t understanding the nuts and bolts of data science, but the outcome - what data science delivers. Kate believes a Data Scientist is only as good as their ability to explain what they do to others and adapting this to suit the audience. The underlying maths can be complicated but not everyone needs to understand it in-depth to grasp what it is. All you need to know is what the inputs and outputs are, and what to do with the results.
Stephen, Rob and Kate agree that people shouldn’t be data led, but data informed – the data tells you something but you’re in control of what happens next. Data is often understood and implemented but not monitored. So, models can go askew if left unchecked. You need to take responsibility - data and data tools aren’t immortal.
Kate goes on the explain some data science projects she’s worked on for charity clients since being at Wood for Trees, including creating decision trees and prediction models. She’s recently helped build the high-value prediction algorithm in InsightHub Predict (recently nominated in the Reimagining Fundraising Global Innovation Challenge 2022), which predicts which charity supporters are likely to become high-value donors. This began with 300 variables, which was gradually and methodically narrowed down to 10-20 filters to deliver meaningful results, which goes to show sometimes having less data can be more beneficial than too much.
With the charity sector not being as advanced in technology and having smaller budgets than some other fields, it’s all the more reason to streamline data and work with what you’ve got – we can meet you in the middle and go from there.
Kate ends by explaining what she loves about her data science role and working in the charity sector: “What we’re doing at Wood for Trees matters and it helps people, which drives and motivates me to create better data models. I love seeing how people are adopting more digital and technological skillsets over time and helping to bring modern solutions and applications seen in other fields to the charity sector. Data science is my talent and it’s great to use it in a space that’s helping others, in a sector where people are primed for learning and taking on opportunities to advance, to do more good work and make really impactful change.”
