Table 12.2, 12.12 Item distribution maps

(controlled by MRANGE=, MAXPAGE=, NAMLMP=, ISORT=, T1P#=)

Table

12.5 Item labels with expected score zones

12.6 Item labels with 50% cumulative probabilities

12.12 Item labels, by easiness, with person distribution (same as Table 1.12)

In Table 12.2, the full item names are shown located at their calibrated MEASUREs in Table 13.1, along with the person distribution according to Table 17.1. You can use NAMLMP= or IMAP= to control the number of characters of each name reported. "TSMST" summarize the distributions. An "M" marker represents the location of the mean measure. "S" markers are placed one sample standard deviation away from the mean. "T" markers are placed two sample standard deviations away. MAXPAGE= controls the length of the Table. MRANGE= controls the displayed range of measures. ISORT= controls the sort order within rows. You can adjust these values from the "Specification" pull-down menu and then select Table 12 from the Output Tables menu. Thus you can experiment without needing to rerun the analysis.

Where there are more items than can be shown on one line, the extra items are printed on subsequent lines, but the latent variable "|" does not advance and is left blank.

In subtable 12.12, the items are arranged by easiness. The item hierarchy is reversed.

T1P#= sets the number of persons for each #

Items arranged by measure: Look for the hierarchy of item names to spell out a meaningful construct from easiest (highest proportion-correct-value or highest average rating) at the bottom to hardest (lowest proportion-correct-value or lowest average rating) at the top.

Combining Item maps

1. Run the separate analyses. You may need to adjust UPMEAN= to include extreme person measures.

2. Output an IAFILE= from each analysis to Excel.

3. Copy all the separate IAFILE= into one Excel worksheet with all the measures in the same column

4. Number the items sequentially in column A. The item measures are in column B

5. In a new text file

TITLE = Combined item map

ITEM1 = 1

NI = (total number of items)

NAME1=1 (it will not be used)

NAMELENGTH=1

CODES=01

IAFILE=*

(paste column A and B from the combined Excel worksheet)

&END

(list of all the item labels from the combined Excel worksheet)

END LABELS

1010101010 ... (for NI= columns)

0101010101 ... (for NI= columns)

Analyze this dummy data file and produce Table 12
