Title = Ratings of Scientists (Psychometric Methods p.282 Guilford 1954)

; measurement model

Facets = 3  ; three facets: judges, examinees, items

Non-centered = 1 ; examinees and items are centered on 0, judges are allowed to float

Positive = 2  ; the examinees have greater creativity with greater score

Model = ?B,?B,?,Creativity ; judges, examinees and items produce ratings on "Creativity".

; A bias/interaction analysis, ?B,?B,?, will report interactions between facets 1,

; senior scientists (judges,) and 2, junior scientists (examinees).

; log(Pnijk/Pnijk-1) = Bn - Di - Cj - Fk

; Bn = ability n, Di = difficulty i, Cj = Severity j, Fk = Challenge k,

; Pnijk = probability that child n on item i is rated by judge j with score of k.

Rating (or partial credit) scale = Creativity,R9 ;Creativity is a rating scale with possible categories 0 to 9

1 = lowest ; name of lowest observed category

5 = middle ; no need to list unnamed categories

9 = highest ; name of highest observed category

*

; for Table 4: unexpected observations

Unexpected = 2 ; report ratings if standardized residual >=|2|

Usort = (1,2,3),(3,1,2),(Z,3) ; sort and report unexpected ratings several ways (1,2,3) is Senior, Junior, Trait

; for Table 6: map of elements

Vertical = 2N,3A,2*,1L,1A ;define rulers to display and position facet elements

; for Table 7: table of measures

Arrange = m,2N,0f ; arrange tables by measure-descending for all facets,

  ; 2N = element number-ascending for facet 2,

  ; and 0f = t-statistic-descending for facet 0 (bias interactions)

Inter-rater = 1 ; facet 1 is the rater facet

; for Table 13: bias/interaction report

Zscore = 1,2  ;report biases greater in size than 1 logit or with z>2

; Output files

Score file = GUILFORD.SC ; score files .SC.1.txt, SC.2.txt and .SC.3.txt produced

Labels =

1, Senior scientists ; name of first (judge) facet
