Table 10.4 Item most-misfitting response strings

Table 10.4 displays the unexpected responses in the most-misfitting item-response strings.

 

 

In this Table, the item (rows) are sorted:

OUTFIT=Yes

Sorted by Outfit Mean-square descending

OUTFIT=No

Sorted by bigger of Outfit Mean-square and Infit mean-square descending.

 

The person (columns) are sorted by measure. The most able person (highest-scoring) is on the left. The person entry-numbers are in each column (vertically). In the Figure, the first is person 41. The persons shown are those with the most-unexpected responses. UCOUNT= sets the maximum number of persons to report. LINELENGTH= controls the width of the table. "high" indicates where we expect to see high observations. "low" indicates where we expect to see low observations. Expected observations are replaced by ".'.

 

Each row contains:

Item entry number

Item label

Item outfit mean-square

Item letter (A-Z) in Table 10.1.

The responses to the items:

0, 1, 2 and numeric values

Scored unexpected-responses

Expected responses, standardized residuals < |2|

(blank)

Missing data

 

The 26 items at the top of Table 10.1 are shown, excluding those with no unexpected responses on the displayed persons.
