P.D.A.T. (Piazza Data Analysis Tool)by Varun Agarwal and Aashish Lalani
Co-Advised By Swapneel Sheth, Arvind Bhusnurmath, Benedict BrownIntroduction
P.D.A.T is a tool to be used to analyze student/TA behavior in classes with available piazza data. Our objective was to create an application that can be used by professors and teachers to improve class experience in the future. We developed a set of hypothesis to study and research with the available data.We analyzed CIS110 data with certain statistical models in mind. P.D.A.T can take raw piazza data and produce datasets that helped us in our study and can be used in the future by others..
• Perform statistical evaluations on more hypothesis which involve more data sources such as “Higher Attendance in Office Hours leads to higher grades”.
• Tool can be used by students and teachers for improvement of classes since it is generic to any class with available Piazza data.

Sample Output Graphs
New TAs answer more questions on average! However certain returning TAs answer more than everyone! (Head TAs?) Solution?
Engage old TAs!
Do New TAs answer more posts than old TAs?
Does number of posts spike during class milestones (exams and homework deadlines)?
Yes! Posts spike 150% or more on milestone days! Solution? Give more TAs piazza duty on these days!
Do a few students answer all the questions?
Inequality between number of answers is greater than income inequality in the country!
By when can you expect an answer?
A day at most?
