Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Teacher and peer marks did not differ significantly (t-tests, H0 accepted at 5%) and correlated highly (Pearson 0.88-0.91) across two exams. → Bouzidi 2009

q2 · i? · associational · r1
Comparison of teacher marks (TM) with peer marks (PM) and peer-plus-self marks (SPM) on the CA-2006 exam (68 papers) and CA-2007 exam without Q7 (94 papers); all four t-tests accepted H0 at the 5% level, with Pearson correlations of "0.88 0.91 0.89 0.91" and Cohen's d of 0.11, 0.11, 0.03, 0.06 as printed in Table 5.
"The correlation coefficients between the teacher's marks and those of the peers are high (0.90±2). The “T-Test”, applied to the marks awarded by the teacher and the marks awarded by peers, is positive."

Related Claims¶
- Item analysis flags items whose marking instructions mislead peer assessors — related
- Combining peer assessment with self-assessment brings marks closer to the teacher's marks — related
- Peer marks and grades show acceptably high reliability with teachers' marks in most comparison studies, but a substantial minority report low reliability — a broader claim this one bears on
- Peers slightly under-mark their comrades' papers while self-assessors over-mark their own — reports the opposite
