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? Using the critical ratio for high-score versus low-score group differences (top and bottom 27%), eight items with nonsignificant or CR < 3 differences were removed, leaving 56 items. → Liu Qingqi 2026
Evidence¶
Liu Qingqi 2026¶
Liu Qingqi, Miao Wenjiao, Li Jingjing, Lei Yuju. (2026). The Six-Facet Artificial Intelligence Literacy Questionnaire (SFAILQ): Assessing AI Literacy in Adolescents, Young Adults, and Midlife Adults. Behavioral Sciences, 16(7), 1110. https://doi.org/10.3390/bs16071110
q2 · i? · design · r2
Item discrimination analysis in Sample 1 (N = 1217): participants ranked by total score, top 27% versus bottom 27% compared per item; items retained if absolute CR exceeded 3.00. Item 9 had an absolute CR of 9.23 and was retained.
"As a result, we removed a total of eight items (items 6, 7, 8, 16, 29, 30, 34, and 56), leaving a final count of 56 items."
