Hi all,
I have a segmentation typing tool (6 scalar questions) and have just included the necessary questions in my survey. I would like to create an embedded data field that automatically calculates which segment my respondents belong in based on their answer to these 6 questions.
The segments are based on top 3 box (%8-10) scores. I had already created an embedded data field for all 6 variables so if %8-10 are given these new variables =1 (TT1_T3B through TT6_T3B).
Below is the java code that I want to use to create the actual segment variable.
var segment1 = -3.8 + (TT1_T3B * 5.0) + (TT2_T3B * 0.6) + (TT3_T3B * 0.4) + (TT4_T3B * 0.9) + (TT5_T3B * 0.8) + (TT6_T3B * 1.0)
var segment2 = -14.7 + (TT1_T3B * 4.4) + (TT2_T3B * 5.0) + (TT3_T3B * 5.5) + (TT4_T3B * 5.2) + (TT5_T3B * 4.8) + (TT6_T3B * 6.9)
var segment3 = -6.8 + (TT1_T3B * 2.6) + (TT2_T3B * 3.5) + (TT3_T3B * 1.1) + (TT4_T3B * 4.9) + (TT5_T3B * 4.4) + (TT6_T3B * 1.6)
var segment4 = -1.6 + (TT1_T3B * 0.9) + (TT2_T3B * 0.5) + (TT3_T3B * 0.2) + (TT4_T3B * 2.0) + (TT5_T3B * 0.8) + (TT6_T3B * 0.8)
maxSegment = Math.max(segment1, segment2, segment3, segment4);
if (maxSegment == segment1) 1;
else if (maxSegment == segment2) 2;
else if (maxSegment == segment3) 3;
else if (maxSegment == segment4) 4;
else NaN;
Any idea how to go about creating this variable in Qualtrics?
Thanks!!!
We can use qualtrics Math operation and branch logic for this.
Shashi Could you provide some more details on this?
michaelperri ,
In the survey flow before your JavaScript, add the segment embedded data field (don't assign a value):
Set Embedded Data: segment
Your JavaScript should assign a segment variable:
var segment;
if (maxSegment == segment1) segment = 1;
...etc...
At the end of your JavaScript:
Qualtrics.SurveyEngine.setEmbeddedData("segment",segment);
Thanks, TomG
Where do Age, FinHlth2, FinHlth3, etc. come from?
magSegment = ...should have a var in front of it.
All statements should end with a semi-colon.
So I've updated my code and the script is running but it's not updating the embedded data field.
https://community.qualtrics.com/XMcommunity/discussion/comment/51087#Comment_51087Those are my question labels
Regarding your updated code, it doesn't work like that. Assuming the JS is on a different page than the other questions (Age, FH1, etc.), you need to pipe those values into your JS and convert them to values. For example, if age is QID1 then:
var Age = Number("${q://QID1/SelectedChoicesRecode}");
Again, all statements should end with the semi-colon and you are missing
varin front on
maxSegment = ...
Thanks, TomG. I'm new to JS and pulling from what I can find and editing as I can.
I've updated the code as follows and am now getting a token Illegal error. It appears the editor is not recognizing FH2 thru FH8 as variables
Qualtrics.SurveyEngine.addOnload(function()
{
var segment;
var Age = Number(“${q://QID12/SelectedChoicesRecode}");
var FH2 = Number(“${q://QID3/SelectedChoicesRecode}”);
var FH3 = Number(“${q://QID4/SelectedChoicesRecode}”);
var FH4 = Number(“${q://QID5/SelectedChoicesRecode}”);
var FH5 = Number(“${q://QID6/SelectedChoicesRecode}”);
var FH6 = Number(“${q://QID7/SelectedChoicesRecode}”);
var FH8 = Number(“${q://QID9/SelectedChoicesRecode}”);
var Barely = 0;
var Free = 8.248 + (Age * .408) + (FH2 * 0.832) + (FH3 * 0.775) + (FH4 * 0.983) +
(FH5 * 0.621) + (FH6 * 0.803) + (FH8 * 0.843);
var Comfy = -3.265 + (Age * .580) + (FH2 * 0.916) + (FH3 * 0.790) + (FH4 * 1.033) +
(FH5 * 0.695) + (FH6 * 0.810) + (FH8 * 1.025);
var Frugal = 1.518 + (Age * .393) + (FH2 * 0.743) + (FH3 * 0.486) + (FH4 * 0.383) +
(FH5 * 0.599) + (FH6 * 0.368) + (FH8 * 0.708);
var Juggle = 4.112 + (Age * .470) + (FH2 * 0.276) + (FH3 * 0.174) + (FH4 * 0.254) +
(FH5 * 0.147) + (FH6 * 0.057) + (FH8 * 0.246);
var Living = 7.883 + (Age * .419) + (FH2 * 0.758) + (FH3 * 0.725) + (FH4 * 0.947) +
(FH5 * 0.608) + (FH6 * 0.649) + (FH8 * 0.766);
segment = Math.max(Barely, Free, Comfy, Frugal, Juggle, Living);
Qualtrics.SurveyEngine.setEmbeddedData("segment",segment);
});
https://community.qualtrics.com/XMcommunity/discussion/comment/51104#Comment_51104The quotes in Age, FH2, etc. are curly double quotes instead of regular (straight) double quotes.
Thanks, TomG. Your comments have been incredibly helpful.
I do have one last question: I've gotten the code set that it is now updating the embedded data field as I want it to, however, I'm trying to get it to display that value in the Text/Graphic question that I have the JS written into and I haven't been able to get it to do so yet. I'm using the pipe text feature and this text ${e://Field/segment} which is what the UI points me to.
Code:
Qualtrics.SurveyEngine.addOnload(function()
{
var segment;
var e = 2.71828182845904;
var Age = Number('${q://QID12/SelectedChoicesRecode}');
var FH2 = Number('${q://QID3/SelectedChoicesRecode}');
var FH3 = Number('${q://QID4/SelectedChoicesRecode}');
var FH4 = Number('${q://QID5/SelectedChoicesRecode}');
var FH5 = Number('${q://QID6/SelectedChoicesRecode}');
var FH6 = Number('${q://QID7/SelectedChoicesRecode}');
var FH8 = Number('${q://QID9/SelectedChoicesRecode}');
var maxseg;
var Barely = Math.pow(e,0);
var Free = Math.pow(e,(8.248 + (Age * .408) + (FH2 * 0.832) + (FH3 * 0.775) + (FH4 * 0.983) +
(FH5 * 0.621) + (FH6 * 0.803) + (FH8 * 0.843)));
var Comfy = Math.pow(e,(-3.265 + (Age * .580) + (FH2 * 0.916) + (FH3 * 0.790) + (FH4 * 1.033) +
(FH5 * 0.695) + (FH6 * 0.810) + (FH8 * 1.025)));
var Frugal = Math.pow(e,(1.518 + (Age * .393) + (FH2 * 0.743) + (FH3 * 0.486) + (FH4 * 0.383) +
(FH5 * 0.599) + (FH6 * 0.368) + (FH8 * 0.708)));
var Juggle = Math.pow(e,(4.112 + (Age * .470) + (FH2 * 0.276) + (FH3 * 0.174) + (FH4 * 0.254) +
(FH5 * 0.147) + (FH6 * 0.057) + (FH8 * 0.246)));
var Living = Math.pow(e,(7.883 + (Age * .419) + (FH2 * 0.758) + (FH3 * 0.725) + (FH4 * 0.947) +
(FH5 * 0.608) + (FH6 * 0.649) + (FH8 * 0.766)));
maxseg = Math.max(Barely, Free, Comfy, Frugal, Juggle, Living);
if (maxseg == Barely) segment = 'Barely';
else if (maxseg == Free) segment = 'Free';
else if (maxseg == Comfy) segment = 'Comfy';
else if (maxseg == Frugal) segment = 'Frugal';
else if (maxseg == Juggle) segment = 'Juggle';
else if (maxseg == Living) segment = 'Living';
else NaN;
Qualtrics.SurveyEngine.setEmbeddedData("segment",segment);
});

You can't set and pipe a field on the same page. Pipes are resolved before the page is sent to the browser.
If you add a to your question text, you can update it with JS:
Then:
jQuery("#"+this.questionId+" .segment").html(segment);
Thanks, TomG. I really appreciate all the help.
TomG,
I’m trying to determine the steps for this process. Are they the following?
(1) Create the segmentation typing tool with a Javscript code
(2) Click on survey flow, “add a new element here,” and “embedded data”
(3) Type in the Javascript code in “create a new field or choose from dropdown”
Are those the steps or am I missing something? Thanks.
Tom,
I’ve explored the idea of creating a hidden question using javascript where the segments created from embedded data can be associated with a question so that the data can appear on the results tab without having to filter. Here’s the hidden question that I have created and I used survey flow to create embedded data for each segment.
Here is what I see when I try to use the javascript function for this question.
For the javascript, where would I input this.setChoiceValue (choiceId) or jQuery('#'+this.questionId).css("visibility","hidden") if I wanted to make this question a hidden question? Thanks.
Thanks
