  9. Why are secondary data important? “Data are unlike other tools of the research endeavour. They provide the raw material from which information and knowledge can be created. By their nature, data allow for exploration of topics of interest to the researcher. Unlike printed [or statistical] tables which, like a postcard, provide a picture of one view of a larger phenomenon, data can act as a camera, allowing the researcher to manipulate the background, change the foreground and more fully investigate the object under study.” Watkins, Wendy, and Ernie Boyko, "Data Liberation and Academic Freedom" Government Information in Canada/Information gouvernementale au Canada 3, no. 2 (1996). [http://www.usask.ca/library/gic/v3n2/watkins2/watkins2.html] Research Data Management Seminar, November 10, 2009

Does the provider make this information available? • Who is the sponsor of the data collection? • What is their agenda? • E.g., a political party, Elections Canada, or a car manufacturer all have specific agendas affecting “the message” and “the data” CRM 6325
