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 Study 1 (n = 69), parallel analysis indicated three components, and after removing two GCL items the final solution consisted of 15 items underlying three components explaining 74.3% of the total variance. → Krieglstein 2023

q2 · i? · design · r2

Principal component analysis (Study 1) of the 17-item catalog with oblique rotation and parallel analysis, with 69 university students rating wastewater-treatment learning material. The final solution "consisted of 15 items underlying three components that explained 74.3% of the total vari- ance".

"The final solution con- sisted of 15 items underlying three components that explained 74.3% of the total vari- ance which is above the recommended value of 50% (Henson and Roberts, 2006)."
