Several different versions of the questionnaire are possible and highly recommended, as this is one of the main untapped potentials of the 1KA tool (basic recommendations).
Different versions of the questionnaire can be produced in two ways. It depends on whether the data from the different versions of the questionnaire should be collected separately or together in a single database.
1. Data from different versions of the questionnaire in one database
The different versions of the questionnaire are created within a single survey and separated by the use of IF statements (conditions). The use of conditions is only available for users of the 2KA and 3KA packages for individuals, and for users of the business packages for groups. For each version of the questionnaire, we create a new condition (we insert all the questions for one particular version into this condition), where we select 'Random groups' as the variable, and then we specify 'Number of groups' (e.g. 2 if we want to have 2 groups), and then we specify which group gets this version or this part of the questionnaire (e.g. 1 and 2).
The condition operates based on the respondent's sequence number (recnum) using integer division by module and remainder, so each respondent gets only one version of the questionnaire. For more details, see the manual Creating sub-samples: half of the respondents gets one question, while the other half a different question.
2. Data from different versions of the questionnaire in separate databases
In this case, we have to create a completely separate survey for each version of the questionnaire, or copy the survey using the 'Copy survey' icon located in the right corner above the questionnaire. We then create another (meta) survey to send to the respondents. In this survey, we turn off the introduction page (Introduction) and set the IF conditions using 'Random Group', the same as in the previous example. Inside each condition, we create a Label question type, which contains a link to one of the surveys in addition to the address.
