![]() ![]() Value Labels – Assigns response labels for each variable.Variable Labels – Assigns descriptive labels to variables in the dataset.Data List – Defines the variable names, column locations and data formats.It includes the ASCII data file name and the path the program will use to locate it. File Handle – Creates a unique file definition to be referenced in the program.SPSS Commands That Every SPSS Syntax File Should Have Since no structure is included in an ASCII data file, an SPSS syntax file (also known as a setup file) must be created to instruct the software on where to go to get particular variables (questions). Bringing ASCII Data into SPSS SPSS Syntax File If this number is “1” the file is a single record file, otherwise it is a multi-record file. Refer to the codebook cover page where the number of records per respondent is listed. Is the ASCII Single Record or Multi-Record? Multi-Record – respondent’s output is recorded on more than one line or row.Single Record – respondent’s output is recorded on one line or row.The “mapping” information for the characters comes from the codebook discussed in step one above. They contain no formatting information–just rows of characters. ASCII Data FilesĪSCII data files are often referred to as “text” files or “plain text” files. We will focus on “determining the appropriate SPSS Syntax file needed” and “creating the required SPSS Syntax file”. Weighting – If the codebook indicates there is a weight variable, the analysis should be run weighted in order to make the responses be representative of the population surveyed, and to replicate the responses published by the survey organization.Use the examples and rules provided to create the required SPSS Syntax file.Based on the number of records per respondent listed on the codebook cover page, determine the appropriate SPSS Syntax file needed (single record or multi-record).Download both the documentation and data file at the same time.The back of the codebook includes a dump of the data referred to as an x-ray which shows the un-weighted number of cases in each punch for each column. Some studies may include a list of variables and the card and column location for each variable. The codebook/questionnaire includes the question numbers, question text, responses including the codes and labels, as well as the card and column locations for each variable. The study methodology and any usage notes may also appear. It includes information regarding the survey including the study number, title, name of the survey organization that conducted the study, the sponsor (if applies), the field dates, type of sample(s), sample size, type of interview, weight information, and number of records per respondent. The codebook fully describes the dataset. Review the study documentation (also referred to as the codebook) first to identify the questions you want to analyze in SPSS.Also, please note that this procedure is based on Roper Center datasets only and we recommend the use of the SPSS Syntax file over the SPSS Wizard for more satisfying results. Please note the assumptions that went into the creation of this document: it is assumed the user has access to SPSS software and has some basic SPSS experience.
