List Question

June 18, 2016

Description

A list question expects an open list of answers. Each answer can contain alphanumeric characters (A-Z, a-z,0-9) and basic punctuation symbols. By default the enumerator can add up to 40 items; however you can limit the number of items that can be listed by defining the maximum number of answers.

For example, very frequently national household surveys ask the enumerator to list all the household members, instead of first asking for the total number of people living in the household and then for their names. Therefore, because the household size is unknown it can be any number. You would define the question in the following manner: “List the names of the people who live in the household” without limiting the household size.

On the other hand, there are some questions where you would like the answer list to be limited to a certain number. For example, in a survey measuring household food security vulnerability, one of the questions asked may be “List up to four threats that make your household at risk of being food insecure”. For this question you would assign a maximum number of answers to equal four.

Options

 

Maximum number of elements

By default the field of Maximum number of list elements is blank. This means that the default maximum number of listed answers assigned by the system is 40. You may want to limit the number of answers that can be submitted. For example, consider the case of a marketing survey where you are only interested in the interviewee’s two most favorite colors.

In order to assign a maximum number of answers lower than the default number, you need to type the corresponding number in the Maximum number of list elements field.

On a tablet, a text field is shown until the maximum number of answers is listed. 

A text field is no longer shown once the maximum number of answers has been listed.

 

Export

The listed answers are exported in text variables in a tab-delimited file. The system creates as many variables (columns in tab-delimited file) as the total number of possible answers. For example, if the maximum number of answers has been defined as 5, then there will be 5 variables in the tab-delimited file. If the maximum number of answers has not been defined, the system will automatically create 40 variables for the question. The exported variable names are built by linking the question’s variable name and an index number (starting from 0).
