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.

q1 i? The cephalic index computed from length and breadth head measurements exhibits fluctuations in both children, and the parents' cephalic indices were 78.8 and 81.8. → King 1930

q1 · i? · associational · r1

Head length and breadth were taken with callipers and the cephalic index computed and plotted in the charts. The article reports fluctuations in both cases and gives the parental indices as 78.8 and 81.8; precautions were taken to measure underneath the hair.

"It will be noted that this exhibits some interesting fluctuations in both cases. In connection with this data it will be of interest to know that the cephalic index of one of the parents is 78.8 and of the other 81.8."
