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? Offner holds that subjective symptoms afford an unreliable measure of fatigue. → G. M. W 1910
q2 i? Physiological tests of strength, endurance, movement rate, pulse, respiration, and ocular accommodation have given valuable suggestions but no reliable method for measuring fatigue. → G. M. W 1910

q2 · i? · review · r2
The review summarizes Offner's monograph analysis of fatigue measurement: subjective symptoms are unreliable, and physiological measures, while suggestive, have "not as yet given us a reliable method for measuring fatigue." No quantitative results are printed.
"measurements of pulse, respiration, and ocular accommodation have given us, it is true, many valuable suggestions, but they have not as yet given us a reliable method for measuring fatigue."
Discussion¶
Related Claims¶
- Fatigue depends on age, sex, lesson length and number, time of day, weekday, recesses, holidays, rest, sleep, nature of work, school program, and teacher personality (Offner's laws of fatigue) — related
- Psychological methods of fatigue measurement afford useful average values and reliable information about the course and effect of fatigue (Offner) — related
- Unreliability in an outcome measure reduces the statistical power of treatment-control comparisons — a broader claim this one bears on
- Physiological measures have limited validity for effort, especially for distinguishing data-driven from goal-driven effort — reports the opposite
