Quality Assurance - Data File Information/Dictionary

From Q
Jump to: navigation, search

This QScript shows values, labels, Question Type and Variable Type information for the variables in a data file (i.e., it is similar to the data file information/dictionaries prepared by SPSS and other programs). A text report is shown on the screen, which can be copied and pasted into other applications for viewing or printing.

Example

------------------------------------------------------------------------
The ID that is included in the web address in each recruit's invitation

------------------------------------------------------------------------
Respondent type

Question Type: Pick One
Variable Type: Categorical

Precode		Label

1		normal respondent
2		test respondent
3		designer/tester
------------------------------------------------------------------------

Technical details

This QScript goes through each question in the project and reports:

  • The Question Type of the question.
  • The Variable Type of the first variable in the question.
  • The list of Source Values (original value in the data file) and the label associated with each value. Note that source values are the original values in the data file, and so the display of those values does not reflect any changes (recoding) that you have made in the Q Project.

If a question is Text then the responses are not displayed.

project.dataFiles[0].questions.forEach(function (question) {
    log(separator);
    log(question.name + "\n"); // Print question name
    if(question.questionType.indexOf("Text") != 0) {
 
        log("\r\n" + "Question Type: " + question.questionType); // Print question type
        log("Variable Type: " + question.variables[0].variableType); // Print variable type
        log("\r\nSource Value\tLabel");
        log("---------------------\t---------");

        var cur_value_attributes = question.valueAttributes; // Value attributes for this question
        // Report Source Values and Labels for this question        
        question.uniqueValues.forEach(function (value) {
            log(value  + "\t\t" + cur_value_attributes.getLabel(value)); // Add the code and label to the table
