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? When choosing a best guess of the arm span and stating confidence, the most frequent response category (35%) was a modal idea, although the term mode was not used. → Lyn D English and Jane M Watson 2015

q2 · i? · design · r2

Content analysis of 101 workbook responses to the accuracy/best-guess/confidence question in the first scenario. Table 3 reports 35% mode/frequency, 23% nebulous statement, 12% variation in relation to accuracy, 11% average/central tendency. The top category "contained responses related to a modal idea, although the term mode was not used."

"The most frequently occurring category contained responses related to a modal idea, although the term mode was not used."
