Instructors: Gabriela Cohen Freue, Sara Mostafavi, Estella Qi
STAT 450 and STAT 550 students have worked collaboratively on real case studies brought by researchers from other disciplines. Supervised by graduate students and instructors, STAT 450 students performed various statistical analyses to address their “client’s” questions. STAT 550 students created GitHub repositories to host R-codes, reports, and discussions, enabling an effective communication between collaborators. Results from six exciting projects are presented in this poster session.
Poster 1: Honey Bees
Collaborator: Renata S. Borba (Postdoctoral Research Fellow, Agriculture and Agri-Food Canada)
STAT450: Candy Chow, Alice Hong, Dee Wang, Fan Wu; STAT550: Rachel Lobay, Saif Syed
To explain the effect of pathogens and parasites on honey bee colony-level traits, several bee colonies across Canada were monitored over a two-year period. Accounting for potentially confounding traits, we identify pathogens that affect economically valuable traits, such as honey production.
Poster 2 and e-station: International Experiential Learning
Collaborator: Tamara Baldwin (Office of Regional and International Community Engagement, UBC)
STAT450: Sheng Di, Xinwei Kuang, Hantao Mai, Jinfu Que; STAT550: Lucy Bellemare, Ana Cecilia Leon Morales
The Office of Regional and International Community Engagement (ORICE) at UBC conducted an online survey among alumni of their international experiential learning program to assess its long-term impact. We analyze whether the questionnaire measures the constructs of interest and visualize how well the data collected corresponds to the intended four areas of personal growth.
Poster 3: Particulate Pollution in Lavington, BC
Collaborator: Tom Caope-Arnold, Simone Runyan
STAT450: Jessie Li, Akbar Qazi, Ash Sandhu, Haihong Xie; STAT550: Glenn McGuinness, Tom Peng
The impact of the Pinnacle Renewable Energy pellet plant in Lavington, BC, on the air quality is monitored by the Ministry of Environment via a stationary monitoring station downwind of the factory and a smaller monitoring station upwind. The results from the initial analysis by the Ministry are contentious. We highlight issues with their analysis and how these potentially affect the conclusions whether the factory is a source of pollution.
Poster 4: StandUp UBC
Collaborator: Professor Guy Faulkner (School of Kinesiology, UBC)
STAT450: Sally Bagk, Tiandian Chen, Yuliyan Kopystynski, Alvin Mangaoang ; STAT550: Xinglong Li, Lin Zhang
The StandUp UBC study aims to determine the effect of standing desks on several emotional states. We show that a reduction in sitting time between the start of the intervention and three months into the intervention is associated with positive changes in some emotional states.
Poster 5: Women’s Participation in Engineering
Collaborator: Agnes d’Entremont (Instructor of Mechanical Engineering, UBC)
STAT450: Cameron Huynh, Yueyan Li, Summer Shan, Qiyu Wu; STAT550: Malvika Mitra, Yichen Zhang
The goal of the project is to assess the impact of the introduction of societal engineering disciplines on women’s participation in engineering. We analyze the proportion of females in engineering programs in US engineering schools before and after a new discipline is introduced. Our results suggest that overall female enrollment is higher after the introduction of a societal discipline. Furthermore, some traditional disciplines show increased enrollment after the introduction of certain societal disciplines.
Poster 6: Patterns in WebWork Submissions
Collaborator: Agnes d’Entremont (Instructor of Mechanical Engineering, UBC)
STAT450: Siqi Cheng, Stella Song, Qifan Tang, Ziqi Xu; STAT550: Giorgio Sgarbi, David Xu
In this project we aim to identify patterns in the usage of the online homework submission tool WebWork, and whether there is an association between these patterns and students’ final grades. From homework submissions in two engineering courses, we identify three distinct submission patterns and find evidence that students that submit homework earlier also have higher final grades.
