The creation of multiple versions of a questionnaire is possible and highly recommended since it is one of the major untapped advantages of the 1KA application (The most frequent survey creation mistakes >> ).
Different versions of the questionnaire can be prepared in two ways, depending on whether we want data from the different versions of the questionnaire collected separately or together in a single database.
1. Data from different versions of the questionnaire is collected together in one database
Different versions of the questionnaire are created within one survey and are separated using IF statements (conditions). We create a condition for each version of the questionnaire (we insert all the questions of that particular version into the condition), choosing ‘Random groups’ as the variable and then determining the ‘Groups count’ (e.g. 2, if we wish to create two groups), after which we determine which group will receive this particular version of the questionnaire. (e.g. 1 and 2). The condition is based on the record number of the respondent (recnum), with each respondent receiving only one version of the questionnaire. For more, read 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 is collected separately
We create a separate questionnaire for each version, or we copy the survey with the ‘Copy survey’ icon, which is located in the right corner above the questionnaire. We then create a (meta) survey, which will be sent to the respondents. We then switch off the main page (Introduction) and set IF conditions by using the 'Random groups' option. Within each condition, we add the question type 'Address', which in addition to the introduction contains a link to one of the sub-surveys.
The use of conditions is only available to 2KA and 3KA private package users.
