Pair.txt: 4 facet judge pairs: Language test

In this Foreign Language reading test, examinees read two text passages. The first passage (chosen at random from many available passages) is heard by a judge. The examinee than moves to an intermediate waiting room. Then the examinee is heard by a different judge on a different, randomly selected, passage. Examinees are assigned to the next available judge at each stage. Rating is on a holistic 1-5 category scale.

 

Facets specifications and data (in file Pair.txt):

 

Title = Paired-judge Reading Test  ; the report heading line

Facets = 4   ; examinees, texts, raters, time-point

Converge = .5, .1  ; converged when biggest score residual is .5 and biggest change is .1 logits

Positive = 1, 3  ; examinees are able, raters are lenient

Noncenter = 1   ; examinee measures relative to texts, raters, etc.

Umean = 50, 5   ; user-friendly logit-rescaled measures: logit = 50 + 5 * logit

Arrange = F,m   ; tables output in Fit-ascending (F) and Measure-descending (m) order

Usort = U   ; sort residuals by unexpectedness

Vertical = 1A, 3A, 2A ; Display examinees, raters, texts by name

Model =

?,?,?,?,reading  ; basic model: raters share the 5-point rating scale

?,?B,?,?B,reading  ; text x time-point interactions: does practice help?

*

Rating scale = reading,R9,K ; 5 category scale, K=keep intermediate unobserved categories

1 = incoherent  ; sounding out the words, or worse

5 = fluent   ; as a native speaker

*

99,6,3,1, 3

99,2,1,2, 5

 

In Table 7, the "Fair Average" reports a standard rating for a standard context:

 

 

Here, Kallen has a higher observed average score of 3.0, but lower "Fair Average" score of 2.14 because he read out easier passages to more lenient judges.
