Bethan Donovan

Bethan is a passionate Tableau, Alteryx and PowerBI consultant with a unique background in Physics and a deep interest in algorithms and data visualisation. She holds a Master's in Physics from the University of Bristol and initially worked as a Physics technician in a college. While her degree embedded a love for mathematics, it was her journey into crochet and knitting that sparked her interest in data. Bethan began writing her own algorithms to simplify pattern design and sought out data sources on body measurements to create customizable, inclusive crochet patterns.

Bethan has previous experience with data visualisation in an experimental sense, but through the application process, she discovered a genuine passion for transforming complex data into meaningful insights. Since then, she has honed her skills in Tableau, Alteryx and PowerBI, applying them to a variety of projects to streamline data workflows and create interactive visualizations that help clients make informed, data-driven decisions.

Bethan’s passion for sustainability and plus-size fashion influences her approach to data analysis, as she seeks to make systems and designs more inclusive and accessible. She enjoys blending creativity and technology to solve problems, and hopes in future to combine data visualisation skills and her own custom patterns to push a modern and mathematical perspective to fibre arts.

With a unique blend of technical expertise and creativity, Bethan is excited to continue exploring the potential of data to drive innovation and inclusivity.

How to use box plots in tableau
Box plots can be an excellent way to visualise the distribution of data points across a selected measure. Box plots allow you to see the median, upper and lower interquartile range (IQR) , and the whiskers extend to 1.5 times the IQR, which allows you to identify any outlying datapoints
