Experimental Uncertainty Estimation and Statistics for Data Having Interval Uncertainty: Sandia Report SAND2007-0939

164 p. Figures. Glossary. References. The authors were associated with Applied Biomathematics of Setauket, New York. This report addresses the characterization of measurements that include epistemic uncertaintites in the form of intervals. It reviews the application of basic descriptive statistics to data sets which contain intervals rather than exclusively point estimates. It describes algorithms to compute various means, the median and other percentiles, variance, interquartile range, moments, confidence limites, and other important statisitics and summarizes the computability of these statistics as a function of sample size and characteristics of the intervals in the data. The report explores the tradeoff between measurement precision and sample size in statistical results that are sensitive to both. Very good. Cover has slight wear and soiling.
