Module 7 :: Statistics
Topic 1 :: Introduction
Statistical Interpretation of the Evidence
Typically there are three possible laboratory outcomes:
- If the DNA profiles from the evidentiary and known samples are consistent at each locus, laboratory analysts can interpret this finding as a "match," "inclusion," or "failure to exclude."
- If the two profiles are not consistent at each locus, the finding can be interpreted as a "nonmatch" or "exclusion."
- If there are insufficient data to support a conclusion, the finding is often referred to as "inconclusive."
For a review of the laboratory interpretation of DNA evidence, refer to Module 6.
