Stopper questions are used for to measure time from a beginning of an event. For example:
“Count how long does it take from the moment the candidate start looking at the product until he finished”
Each question has a set of tabs; each tab is used for different configurations – let’s go over the tab’s.
The View tab
In the view tab you can configure the basic components of a question, such as its body text and its answers.
Question Type & General Settings
In the main panel, you can set the questions type, its textual color and formatting.
In the bottom panel, you can Clear the questions content, add a new question of the same type right after the current one and quickly navigate between questions:
The ‘Question’ Tab
Under the question’s tab, within the View tab, you can define the Questions Body Text and the surveyors instructions if any.
Defining The Questions Text
The text written in the question’s tab is the body text that will be displayed to the surveyor.
The surveyor instruction box, allows you to configure textual instructions for the surveyor that will be formatted differently than the body text.
Here I configured my body text to be:
“Watch at possible candidate that stop near the product”
And the Surveyor Instruction Text to be:
“ INTERVIEWER: Count how long does it take from the moment the candidate start looking at the product until he finished”
The ‘Topic’ Tab
Each topic represent a stopper.
When pressing the START button all stoppers will be started.
Then the LAP button will appear, and choosing it will stop the first stopper while the one after it will keep running.
The Rules Tab
In the rules tab you can define Entrance Rules, Validation Rules and Branching rules.
For more detail please see the following tutorials and refer to the scripting guide:
The Scripts Tab
In the Script’s tab you can define your questions Start Script, End Script and enter the advanced scripts for defining more complex functions.
For more detail about Start, End and Advanced scripts, please see the following tutorials and refer to the scripting guide:
The Variables Tab
The Variables Tab is used for configuring variable related properties of a question.
- Variable Name: is the name of the column representing this question when exporting.
- Missing Value: is the value that this question will get if it was not answered or skipped.
- Short ID: Is a short name that is used for ease of readability and is viewable in the Survey Tree next to the Question Index – Short ID’s can also be used as a basis for variable names, please see: How to work with QRef’s & Short ID’s
Variable names can be referenced instead of Indexes by using the correct functions. (Basic Introduction to using VRef and VarName)
The Advanced Tab
The advanced tab allows you to set & configure more advanced properties of a question.
Common usages of the advanced tab:
- Hiding a question from the surveyor:
Allowing\Disallowing ‘No Answer’:
Variables and Exporting Definitions
Q1_STP1 and Q1_STP2 are the variable names of the topics(stoppers).
I pressed the LAP button after 3.406 seconds and finish the last counter after 13.609 seconds.
Common Functions used to retrieve the value
AnswerChoiceIter(CurrQues, index_of_topic(stopper), index_of_iteration)
Retrieve the number of milliseconds counted by the relevant stopper
