11.1 Uncertainties and errors in measurement and results Qualitative data includes all non-numerical information obtained from observations not from measurement. Quantitative data are obtained from measurements, and are always associated with random errors/uncertainties, determined by the apparatus, and by human limitations such as reaction times.

As with all theoretical models, the expected utility model is not without its limitations. One limitation is that it treats uncertainty as objective risk that is,

Get priceThe objective of an uncertainty study is to put bounds on a measurement (x plus/minus some interval). Generally a 95% confidence interval and the t-distribution is used since there are not a lot of observations taken. To do the study use one gage, one part, one part characteristic, and one operator.
