Diagnosticity Analysis

Most Diagnostic Evidence

SRC01-E01 Primary source directly addresses claim

Least Diagnostic Evidence

N/A All evidence is diagnostic

Outcome

Hypothesis supported: H2 — The ~7,000 figure is confirmed by the Guardian investigation, but 'formal academic misconduct cases' slightly overstates: the data includes suspected cases and comes from only 131 of 155 universities contacted.

Hypotheses eliminated: H3 — The figure is real and well-documented.

Hypotheses inconclusive: H1 — Whether all 7,000 are 'formal' cases depends on definition.
