Some commands for a simple multiple-choice assessment using a scored dataset containing 80 items and a 6 digit ID code.
*Qstart
set length=95!page
set width=72!page
data_file Qstart.dat
format items 7-86 ID 1-6
codes 01
set logon >> Log.doc
Key 11111111111111111111111111111111111111111111111111111111111111111111111111111111 !score=1
Title Qstart
Estimate !iter=100;
show !stat= delta >> ShowQstart.doc
itanal >> ItnQstart.doc
QUIT
These commands create a show file and an item analysis file. Plus a log record file. (Delta centres the average of the item locations to zero.)
Many thanks to Dr. Andrew Stephanou (https://works.bepress.com/andrew_stephanou/) who provided the sample syntax for QUEST.
