How to Find Data and Statistics


librarian picture  


Introduction
This guide will help you to identify and locate sources for data and statistics. Keep in mind that although "data" and "statistics" are often used interchangably, there is a difference. Statistics are a form of data, while data in its "raw" form is not statistics.
  • What is data?
    Data include sets of raw numbers, usually with many variables, and with the capability of being manipulated.
    • Example of data

      Think about the census as data about numbers of people in a geographic region. Variables will include such things as male vs female, age, income levels, racial/ethnic background, education, etc. You can manipulate the numbers to answer questions about the data -- for example, does income level correlate with education? Raw data is just numbers – no correlations, no comparisons.

  • What are statistics?
    Statistics are data that has been analyzed in some way – percentages, graphs, charts – also called “statistical data.”
    • Example of statistics

      Statistics are usually presented in graphs or charts so you can visualize the data connections.

      • From the Statistical Abstract
        statistical abstract

        Read the description to find out what the chart and numbers are all about. Where would you go for the raw data? Always look at the source. If you found statistics from the US National Center for Education Statistics, would you trust it? Probably. But you should always evaluate the source.

    • Bias in statistics

      Statistics can be used to make whatever point you want. For example, the statistics Planned Parenthood reports about abortion may be different from those used by the National Right to Life organization. Two groups can take the same data and present it to fit their needs. Always be alert for bias in statistics!

  • When to use which
    • Use statistics … if you need quick facts to make a point.

      * If your point is that more males than females report bringing weapons onto campus, you can find statistics to support your argument.
      * If you're arguing that the price of textbooks has been rising, you can find statistics to prove it.

    • Use data … if you need to do in-depth analysis for research

      * If you want to make a correlation between aggressive behavior and gender and video games, you may need to find data and establish your own correlation.
      * If you want to make a point that too much government money is spent on moon exploration, you may need to find data to compare money spent on social issues vs. moon exploration

Sources of Data/Statistics
The following are some of the entities that generate statistics.
  • * Government agencies
    Agencies within the U.S. government (eg, NASA, Census) produce a wealth of data and statistics that are free, available on the Web, and available in many different formats. Access from Google, Library Website, and many other avenues.
  • * Local, National, and International Organizations
    Organizations (eg, World Health Org, American Psychological Association) also provide statistics and data in many formats. Much of it is free, but there may be fees depending on the organization. Access through Google, library databases, and many other avenues.
  • * Researchers
    Researchers, including university faculty, may publish their data and statistics articles or books. Access through library catalog, databases, google scholar, personal request, and many other avenues.
  • * Corporations
    Various companies take existing data from many sources and compile them in elaborate ways for users. These sources usually have a steep cost. Examples of databases the library subscribes to for you include market research databases (Mintel Reports) and company and industry databases (Thomson One).
  • * Data archives
    There are resources that provide statistics on a broad range of topics from a broad range of sources. The ODU Libraries provide access to ICPSR (Inter-University Consortium for Political and Social Research) for statistics in all the political and social sciences from government, academic and private organizations worldwide.
How to Locate these Sources
There are many tools you can use to locate data and statistics. Google, Google Scholar, library and other databases, and government databases and agency websites are readily available to you.
  • Google
    http://google.com

    Often, Google can be a good place to start. You can find government, oganization, and business sites with data available.
    • Search Tips:

      * Within your search statement, include (statistics OR data).

      * To search for government, organization, or educational sites, include - site:.gov, site:.org, or site:.edu

            Example:      "global warming" (statistics OR data) site:.gov

      * You can also use the Advanced Search option to fill in these terms and limiters.

    • Google Scholar
      http://scholar.google.com

      You can try Google Scholar to identify research articles using statistics or data. Some of the articles will include statistics and will identify the researchers for you to contact if necessary.
  • Library Databases
    Some of the library's 300+ databases focus on providing data and statistical reports/tables (some are listed below). Most others are used for locating articles. Like Google Scholar, the subject specific scholarly databases may provide you with research articles that include statistics or data. You may be able to use the statistical data from within the article or use the author information provided in order to contact the researcher for data.

Evaluate Your Sources
  • Be critical: use the CRAAP test when viewing data and statistics.

       Currency: Note that you may not always find statistics up to date -- it takes a while to collect the data and then publish it.

       Relevance: Do the statistics support your topic?

       Authority: Statistics from government agencies should be trustworthy! Always verify the source of the statistics.

       Accuracy: Look at the statistics carefully for obvious errors.

       Purpose: Look for bias. Anyone can take data and present it to suit their argument.
