Copyright © 2014 by The University of Kansas It’s easier and less time-consuming than collecting all the data yourself. Archival data may have already been processed by people with more statistical expertise than you, making it easier to use in analysis. Even with raw data, the basic organization and preparation (transcription of interviews, entry of numbers into a spreadsheet or specific software, etc.) may have already been done, again saving time and resources. It’s quite possible that you can find more information than you’d be able to gather if you did it yourself. Why collect and use archival data?
Copyright © 2014 by The University of Kansas Archival data could touch on important areas you might not have thought of, or identify patterns or relationships you wouldn’t have looked for. It may eliminate the need to correct for such problems as lack of inter-rater reliability or observer bias. Archival data allows the possibility of looking at the effects of your work over time. Archival data can make it possible for small organizations with limited resources to nonetheless conduct thorough evaluation studies. Why collect and use archival data?
