XWIDE= columns per response = 1

Up  Previous  Next

The number of columns taken up by each response in your data file (1 or 2 or more). If possible, enter your data one column per response. If there are two columns per response, make XWIDE=2. If your data includes responses entered in both 1 and 2 character-width formats, use FORMAT= to convert all to XWIDE=2 format. When XWIDE=2, these control variables require two columns per item or per response code: CODES=, KEYn=, KEYSCR=, NEWSCORE=, IVALUE=. Either 1 or XWIDE= columns can be used for RESCORE=, ISGROUPS=, RESCORE= and IREFER=

 

Example 1:        The responses are scanned into adjacent columns in the data records,

                       XWIDE=1        Observations 1 column wide

 

Example 2:        Each response is a rating on a rating scale from 1 to 10, and so requires two columns in the date record,

                       XWIDE=2        2 columns per datum

 

Example 3:        Some responses take one column, and some two columns in the data record. Five items of 1-character width, code "a", "b", "c", or "d", then ten items of 2-character width, coded "AA", "BB", "CC", "DD". These are preceded by person-id of 30 characters.

       XWIDE=2        Format to two columns per response

       FORMAT=(30A1,5A1,10A2)                Name 30 characters, 5 1-chars, 10 2-chars

       CODES   ="a b c d AABBCCDD"                "a" becomes "a "

       NEWSCORE="1 2 3 4 1 2 3 4 "                response values

       RESCORE=2                                rescore all items

       NAME1=1                                person id starts in column 1

       ITEM1=31                                item responses start in column 31

       NI=15                                        15 items all now XWIDE=2

 

Example 4: Scores are entered as hundreds, but are to be analyzed as incrementing by 1

       XWIDE = 4

       CODES = " 100 200 300 400 500 600 700 800 9001000"

       STKEEP = No        ; analyze the ascending scores as ordinal levels
