Most questions in market research are single response: only one answer is allowed (e.g. what is your age?). When a respondent is allowed to give more than one answer for the same question (e.g. Express your level of satisfaction on different phone companies?), the answers are stored in separate variables (one for every phone company). Still, you would like to be able to show all possible answers in one table, instead of producing a separate table for each possible answer.
Multiple response variables are variables created in DataDynamic Reporter in order to show the results of questions with more than one answer allowed in a single table.
+ Category multi-response
A variable was created for each of the number of answers a respondent could give. For instance, if a respondent could name up to 5 brands, five base variables would have been created, each of which containing the possible answers a respondent could give. The first base variable could contain value 2 for instance, signifying a particular brand, and the second variable could contain value 6. If a respondent gave only two answers, variables 3, 4 and 5 would remain empty (or missing).
+ Dichotomy multi-response
For each possible answer category, a base variable is created. The base variables can be coded 1 for that particular answer being given, or 0 if it wasn't. If the respondent can choose from 10 brands for instance, 10 variables will have been created. If a respondent chooses brand 2 and brand 6, base variables 2 and 6 will have a value 1, and the other variables will have a value 0 or missing.
When you are dealing with dichotomous base variables, DataDynamic Reporter asks you to name the 'Count value': the value that will be counted as a valid response for that variable. In the above example (and most cases) count value is equal to 1.
In order to create a multi-response or multi-dichotomous variable, you have to indicate which variables you would like to combine by selecting the questions in the variable list and then clicking on 'Add variable' icon in the Edit toolbar. In the drop down select the correct type of the multiple response variable either categorical- or dichotomous Multiresponse.
After the variable is created it will be available for selection just like any other variable, in the data grid the given answers will be shown as a comma separated list of values.
