✦ Synopsis

W e consider the problem o f assessing the signijcance of trace material which may connect suspect and crime. W e demonstrate the application of statistical method when measured data is subject to random (uncontrollable) components of variability. Through simplified model situations we describe the kind of criteria employed i n the design of appropriate statistical tests. W e examine the consequences of applying a test frequently used in the analysis of forensic data. W e also illustrate the need to apply statistical procedures to the problem o f assessing the evidential importance of implied similarities between trace and source.
