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? Baylor et al. (2003) and Mayer and DaPra (2012) found subjects learned more with an animated than a static persona, while Moreno et al. (2001) and Baylor et al. (2003) found the agent's voice contributes significantly to learning, sometimes more than the animated persona. → W. Lewis Johnson & James C. Lester 2015

Secondhand reporting: this retrospective article attributes these findings to the cited comparison studies without printing their effect sizes, so the designs are not described beyond the comparisons named.
"Baylor et al. (2003) and Mayer and DaPra (2012) found that subjects learned more when the persona was animated than when it was static. Meanwhile Moreno et al. (2001) and Baylor et al. (2003) found that the agent's voice contributes significantly to learning, sometimes more than the animated persona"
