member changes between semesters

Here's some facts instead of a made up ranking. After each Fall and Spring semester panhellenic released the numbers of members of each sorority. There is usually a reduction of members in each sorority between fall and spring. This could be contributed to people graduating early, members leaving college entirely, maybe studying abroad, or maybe they left the sorority because they couldn't afford the dues or maybe they left because they were unsatisfied with their sorority experiences.

So here's the reduction totals for each sorority between Fall 2017 and Spring 2018.

Chi-O reduction of 3 members on the rolls
DDD reduction of 7 members on the rolls
KD & DG reduction of 11 members on the rolls
Pi Phi reduction of 19 members on the rolls
Phi Mu reduction of 22 members on the rolls
AOPi & Kappa reduction of 24 members on the rolls
ADPi reduction of 30 members on the rolls
Theta reduction of 50 members on the rolls
Alpha Phi reduction of 55 members on the rolls
