OSAC Lexicon

The OSAC Lexicon is a compendium of forensic science terms and definitions. This terminology tool was created to help bring consistency and understanding to the way terms are used by the various forensic science. Use of the OSAC Lexicon does not replace the need to reference the original published source.

The terms and definitions in the OSAC Lexicon come from the published literature, including documentary standards and technical reports. It is continually updated with the latest work from OSAC units, as well as terms from newly published documentary standards and standards elevated to the OSAC Registry.

Gradually terms are evaluated and harmonized by the OSAC to a single term. This process results in an OSAC Preferred Term. An OSAC Preferred Term is a term, along with its definition, that has undergone review and evaluation by the FSSB Terminology Task Group and has been approved by the FSSB. The FSSB recommends that subcommittees use OSAC Preferred Terms when drafting standards.

The OSAC Lexicon should be the primary resource for terminology and used when drafting and editing forensic science standards and other OSAC work products

Accuracy
the closeness of agreement between a test result and the accepted reference value. Discussion—In practice, the accepted reference value is substituted for the true value. The term “accuracy,” when applied to a set of test or measurement results, involves a combination of random components and a common systematic error or bias component. Accuracy refers to a combination of trueness and precision.

Accuracy Studies

Studies performed to assess the degree of conformity of a measured quantity to its actual (true) value. In probabilistic genotyping, these are studies performed to establish that the calculations made by the probabilistic genotyping system are correctly executed, and that the results obtained produce the expected likelihood ratio for situations where the calculations can be performed manually or with an alternate software program or application. Such situations include profile results from single source samples, 2-person mixtures with unambiguous major and minor contributors, and 2-person mixtures with equal mixture proportions. However, profile results where the ground truth is not known are not suitable for accuracy studies

Discussion—Factors include the presence of the evidence in a particular location (for example, glass found embedded in the sole of a shoe versus glass found on a shirt), quantity (for example, multiple glass fragments versus a single glass fragment), and condition (for example, pulled hair versus shed hair).

Discussion—Alternative hypotheses of alleged activities may also be part of the factors considered.
