Nonparametric statistical methods.
From 6 consenting patients requiring a medical scan, 3 are
chosen at random to undergo a positron emission tomography (PET)
scan, the others receiving a magnetic resonance imaging (MRI) scan.
Image quality is ranked in order by a hospital consultant from 1
(best) to 6 (worst). Describe how you would test
: scan quality is unrelated to scan method against (i)
:PET scans are better (ii)
:the scans differ in quality depending on whether they are from
PET or MRI. Interpret the finding that the consultant rates the
three PET scans as the three highest quality images.
