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? A pupil's spelling ability can be ascertained quite accurately by any two of the six lists, with a mean variation between scores of 2.2 points based on 519 pupils. → Starch 1910

q2 · i? · associational · r2
Reliability analysis of the author's six-list spelling test: repeated testing of the same pupils with two different lists on successive days showed an average deviation between the two scores of 2.2 points, which the author calls "close agreement"; sample records for fourth-grade pupils on lists 1 and 5 are tabulated.
"On the basis of tests made with 519 pupils, the mean variation between the scores from any two of the six lists is 2.2 points."
Discussion¶
Related Claims¶
- Prior spelling test lists (Ayres, Buckingham) are too easy for better pupils, with more than half of eighth-graders spelling all Buckingham list words correctly — related
- The six 100-word spelling lists are practically identical in difficulty, differing from list 1 by .9 to 3.4 points — related
- Grades overlap massively in spelling: on average 20.8% of pupils reach or exceed the median of the next grade above — related
