Executive Summary:
The Center for Environmental Information and Statistics (CEIS) of the U.S. Environmental Protection Agency (EPA) has prepared a draft “Protocol for Statistical Assessment of EPA Program Office Data Systems for Secondary Purposes”, which in part states that:
The statistical assessment of Agency databases for secondary use purposes will be in two parts:
- a quantitative description of the data in the data bases; and
- a case study using a hypothetical secondary use (in most cases we select the secondary use of “Environmental Status Quality and Trends for a Local Community”).
The National Institute of Statistical Science (NISS) has entered into a Cooperative Agreement with CEIS to assist with the assessment. NISS’s first effort under the Agreement has been to carry out just such a case study, specifically of ozone status and trends for the Research Triangle area of North Carolina. The results of the 1 study are presented in the body of this report.
