What type of uncertainty estimates are derived from information other than statistics?

Type B evaluations refer to uncertainty estimates that are derived from information other than statistical analysis of data. This includes evaluations based on knowledge, experience, manufacturer specifications, or other relevant documentation. Essentially, Type B evaluations utilize all available information outside of statistical data to assess and quantify uncertainty.

These evaluations are particularly important in situations where statistical data may be limited or unavailable. For instance, when calibrating a measurement device, the specifications provided by the manufacturer might inform the uncertainty associated with the device's performance.

In contrast, other types of evaluations, such as A evaluations, are based on statistical analysis of repeated measurements, while other types like D evaluations are not standardized categories in this context. Therefore, understanding the distinction between these evaluation types is crucial for accurately estimating uncertainty in various forensic analyses.
