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.
q4 i0 Students in TLTS schools performed 0.09 standard deviations higher in math than students in comparison schools after two years (p < .001). → Naihobe Gonzalez 2023

q4 · i0 · causal · r?
Same randomized controlled trial of TLTS. The report states the math effect: students in TLTS schools performed, on average, "0.09 standard deviations higher than students in comparison schools (p-value < .001)" after two years — a printed effect size of 0.09 SD, below d = 0.2.
"and in math, on average, 0.09 standard deviations higher than students in comparison schools (p-value < .001)"
