Pro Bono: IEEE Chicago Section Statistician - Part 5

My last post in this series on my pro bono efforts outside of the workplace as Statistician for the IEEE Chicago Section mentioned that I walked the Membership Development Chair through the visualizations of my latest monthly presentation to the team, partially in preparation for his request of me to present to the executive committee. Unfortunately, the executive committee meeting that included a number of presentations by other individuals was already behind its already tight schedule at the outset, and so my presentation time ended up being reduced to 15 minutes.
While my presentation was originally intended to cover some of the visualizations and findings of the past year, delivery probably would have benefited from a scaled down scope that concentrated on data of recent months, including the month of March 2014 which was quite coincidentally the best month across the 8 years covered by the database in terms of total active membership net difference (membership additions less membership deletions), as well as April 2014 which was the first month during this same time period where total active membership "closed the gap" in YOY total active membership.
