Jack Parry

After completing his undergraduate degree in Neuroscience, Jack was unsure where to begin his career and started to explore his options. After several unsuccessful months of searching, he found an interest at the prospect of working in BI. It was at this point that Jack discovered Tableau and became transfixed by its capabilities. After some self tuition of the software and exploration of the community, Jack discovered the Data School. Having enjoyed the statistical element to research projects during his studies, combined with the discovery of the powers of Tableau, Jack knew the Data School was the perfect place to develop his skill set and start his career in data analytics.

Dashboard Week Day 2 – London Marathon #oneinamillion

Creating effective sparklines which highlight weekly change
