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? In the feedback intervention sessions, the Error Rates of all five target classes decreased on average in the 10 seconds after feedback was fired, with the greatest decrease for classRate. → Di Mitri 2022

q2 · i? · causal · r1
Analysis of the feedback intervention study with 10 participants performing two 1-minute sessions each; the authors computed first derivatives of Error Rate 10 seconds before and after feedback firing, finding that "the Error Rates of all five target classes are decreasing soon after the feedback is prompted".
"We found out that, on average, the Error Rates of all five target classes are decreasing soon after the feedback is prompted."
