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? Learning of a wigwag code over sixteen consecutive days furnished a very reliable means of evaluating learning capacity irrespective of school standing, showing wide individual differences, significant acceleration and retrogression, and lower performance for negro girls than white girls as groups. → Baldwin 1911

q2 · i? · associational · r1

Summary of Baldwin's comparative learning study of adolescent delinquent white and negro girls using a wigwag code for "sixteen consecutive days"; the "76 practice curves show a wide range of individual differences and significant periods of acceleration and retrogression," and the negro girls as a group accomplished less work and were less accurate. No effect size is printed.

"B. T. Baldwin's paper is a comparative study of The progress of learning of adolescent delinquent white and negro girls as shown by a wigwag code adapted for this purpose and applied for sixteen consecutive days. He finds this type of material furnishes a very reliable means for evaluating learning capacity."
