  1. The Value and Use of Secondary Data Amy Pienta ICPSR

  2. Why use secondary data? • Kuhn’s (1970) scientific paradigm • Replication and confirmation of results • The foundation of the scientific process is that research should build on previous work, • Sharing data and allowing for replication makes one’s work more likely to be taken seriously and cited more frequently (King et al., 1995).

  3. Why use secondary data? • The nature of large datasets virtually guarantees that a single researcher or group of researchers will not be able to use the dataset to its full potential for a single project. • Utilizing secondary data ensures that resources spent on data collection are put to the best use possible and the public benefit is enhanced. • Great value for students, postdocs, junior faculty (and others)

  4. Secondary Data and Graduate Students • Why graduate students use secondary data • Why graduate instructors use secondary data in classroom • ICPSR disclaimer

  5. Graduate Students Users of Secondary Data at ICPSR

  6. Common Uses of Secondary Data • Class Assignments • Class Papers • Replication • Original Analyses • Student Presentations and Publications • Sole author • Co-authored with faculty • Co-authored with students • Theses and Dissertations

  7. Replication Publication • A replication study is a valuable way to meet the goals of a graduate course (Gary King, 2006) • get published • help professionalize students into the discipline • teach the scientific norms of the free exchange of academic information.

  8. Replication Publication Elements of a replication paper (King 2006) • Address a substantive problem in your field of interest • Begin by locating an article in your field, acquiring the data used in the article, and replicating the specific numerical results in the tables and/or figures in that analysis • Describe the extent to which you were able to replicate the author’s results • After replicating, try to improve the presentation of the original results. • Next, run some controlled methodological experiments designed to advance the state of knowledge about the substantive project.

  9. Secondary Data at ICPSR • Finding Data For Classes, Projects, Papers and Presentations • Basic Search • Browsing the Collection

  10. Preview of Part II • Paula Lantz – American’s Changing Lives • James McNally – National Archive on Computerized Data on Aging • Frank Stafford – Panel Study of Income Dynamics • Felicia LeClere – Minority Data Resource Center and Data Sharing for Demographic Research
