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? The fitted model requires numseen, numseen-squared, numseen-cubed, natt and natt-squared terms beyond the Rasch model's first and last terms. → Anna Helga Jonsdottir 2014

q2 · i? · associational · r2
Statistical model fitting to tutor-web drill data shows the two-parameter Rasch model is insufficient: "the remaining parameters are also statist ically significant and therefore also needed to explain the data at hand".
"The two-parameter Rach model only incorporates the first and last terms in equation 2, but the remaining parameters are also statist ically significant and therefore also needed to explain the data at hand."
Discussion¶
Related Claims¶
- Model-data fit evaluation in IRT is claimed to be crucial for both linear and adaptive tests because item response model goodness-of-fit is relevant to any test purpose — a broader claim this one bears on
