1 sample contained values measured from 9 different hellos, and MD’s sample 1 contained values from 12 different hellos. 7 thus gives us a more realistic picture of how the three speakers actually differ, at least for these two dimensions on these three occasions. 7 is clear: the mean values for each speaker’s three different occasions differ. 2. 7. 7, samples from many more separate occasions would be required to be confident of having something like the true relationship between them. © 2002 Taylor & Francis Once again, the fewer the samples the less is the strength of evidence for or against common origin.
5 Architecture of observation data in forensic speech samples 23 © 2002 Taylor & Francis the values of the population they are taken from (Elzey 1987: 42), we can in fact estimate the true population values from large samples taken from it.

In reality, either the questioned source and the suspect source are the same, or they are not.

Two samples, therefore, whether they come from different speakers or the same speaker, cannot get any closer than minimally © 2002 Taylor & Francis different, whereas there is no upper limit on the amount by which two samples can differ.
