  1. Data Discovery The reference interview

  2. The reference interview • Always begin by clarifying the distinction between statistics and data with your patron. Never assume that the patron clearly knows this distinction. • Asking them if they want statistics or data isn’t a good starting question, though. • Ask a question that will help you understand what they might be seeking using the “frameworks” understanding of data sources...

  3. Frameworks • Table Dimensions: • Geography • Time • Subject content

  4. The reference interview • What does the patron intend to do with the numbers? What is their objective? • Include a statistic or two in a report? • Analyze data? • What geographic area is needed? • What is the smallest geographic area to be described? • What time period is needed? • What subject matter (variables) expressed in numbers is needed?

  5. The reference interview If you determine the patron does need data: • Determine what population (unit of observation) they want to describe. • Do they need aggregate data or microdata? Do they need spatial data? • What software does the patron intend to use? • How would the patron like the data delivered?

  6. Level of service • How much you do depends on the level of service you are offering. • Finding a resource • Retrieving a resource from an online service • Tailoring a product for the patron • Creating a product for a patron (e.g., postal code conversion linkage)
