GPS Question

Description

A GPS question expects a set of geographic coordinates (latitude, longitude, accuracy, altitude), which identify the location of the tablet. This type of question can be answered using a GPS-enabled tablet.

In addition to using a GPS question to get specific locations (e.g. household or enterprise), it can also be used to define the area of a land. An area can be defined by creating GPS questions for each point that defines the land’s area.

List Question

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.

Date Question

Description 

A date question expects a date from the Gregorian calendar as an answer. 

Creating a date question

In Questionnaire Designer,

1. Click on the Question Type box.

2. Select Date from the list displayed.

Numeric Question

Description

A num eric question expects an answer to contain numeric characters (0-9). The answer can be an integer or a real number. You also have the option of assigning the number of decimals places to be accepted in the answer or formatting the answer to language specific thousands and decimal separator. By default a numeric question expects a integer number answer. In addition, numeric questions can be extended with special values as categorical selections.

Text Question

Description

A text question expects an answer to contain alphanumeric characters (A-Z, a-z, 0-9), basic punctuation, symbols, and spaces. The structure of the answer can be defined using a pattern. This may be used for phone numbers, id codes and flight numbers. 

The picture below displays a default text question on a tablet that accepts alphanumeric characters with no specific pattern defined.

General Component Properties

When you select a questionnaire component, you can see its details on the right hand panel. Each component is defined by a set of properties. Some features are common to all questionnaire components, and others are defined for specific components. 

In this article you will learn how to define variable names, variable labels, question texts, question types, interviewer instructions, and conditions. 
 
 

Variable name

The variable name is the unique identifier of a component, which is useful when exporting the data for analysis. It has to start with a letter, but can also contain numbers and the underscore symbol. As it is not needed during the interview, the variable name is not visible on the tablet.
