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? Frame-by-frame video analysis of a student's vertical jump produced a slope estimate of g of -10.1 m/s², which the authors report compares well with the local value of -9.7996 m/s². → Barber et al. 2007

q2 · i? · the article prints no effect size for this finding · design · r2
Numerical analysis of videotaped vertical jump data shown in figure 2, with velocity derived from position data at 30 frames per second. A linear fit to the free-fall region gave "The value of -10.1 m/s 2 is the estimate of g" against the local plaque value of -9.7996 m/s².
"The value of -10.1 m/s 2 is the estimate of g from these data which compares well with the known value of -9.7996 m/s 2 in Santa Clara, CA."
