SUMMARY:Digital Echoes: Understanding Patterns of Mass Violence with Data 
 and Statistics  - Patrick Ball\, Director of Research\, Human Rights Data 
 Analysis Group (HRDAG)
DTSTART:20160919T090000Z

UID:TALK66992@talks.cam.ac.uk
CONTACT:Clare Dyer-Smith
DESCRIPTION:Data about mass violence can seem to offer insights into patte
 rns: is violence getting better\, or worse\, over time? Is violence direct
 ed more against men or women? But in human rights data collection\, we (us
 ually) don’t know what we don’t know --- and worse\, what we don’t k
 now is likely to be systematically different from what we do know.\n\nThis
  talk will explore the assumption that nearly every project using data mus
 t make: that the data are representative of reality in the world. We will 
 explore how\, contrary to the standard assumption\, statistical patterns i
 n raw data tend to be quite different than patterns in the world. Statisti
 cal patterns in data tend to reflect how the data were collected rather th
 an changes in the real-world phenomena data purport to represent.\n\nUsing
  analysis of killings during Peru's civil war\, homicides committed by pol
 ice in the US\, killings in the conflict in Syria\, and homicides in Colom
 bia\, we will contrast patterns in raw data with estimates total patterns 
 of violence—where the estimates correct for heterogeneous underreporting
 . \n\nThe talk will show how biases in raw data can be addressed through e
 stimation\, and explain why it matters.\n\n\nRegistration for this seminar
  will close at 17:00 on Friday 9 September 2016. See http://www.bigdata.ca
