Multiple Banks of Statements in Matrix

On the page before the matrix, add 5 multiple choice questions (one for each sport) where the choices are the teams. Use Advanced Randomization on each to display 2 teams evenly presented. Use JS to hide each question.

Add all the teams to your Matrix question and use display logic on each statement based on whether the team was displayed in the MC question on the previous page.

Thanks for this technique! I’m using this code to hide the questions:

Qualtrics.SurveyEngine.addOnload(function() {
jQuery("#"+this.questionId).hide();
this.clickNextButton();
});

Qualtrics.SurveyEngine.addOnReady(function()
{
	/*Place your JavaScript here to run when the page is fully displayed*/

});

Qualtrics.SurveyEngine.addOnUnload(function()
{
	/*Place your JavaScript here to run when the page is unloaded*/

});

With the follow-on question, I figured out that by using “Display Logic” and retyping the whole list (every team from all five hidden banks), I can then set it to: 

TEAM A

Display this Choice only if the following condition is met:

 

Question > QuestionID > TEAM A > Is displayed

But I have to do this Y*X times, where Y is the number of hidden questions and X is the number of teams in each question.

Is there a more streamlined way to set the matrix to display only answers that were present on the previous page or block?

Unfortunately, there isn’t a more streamlined way. Under more normal conditions carry forward would be the more streamlined approach but because you need to use multiple questions for randomization that won’t work.

BTW, presumably you have all five hidden questions on the same page by themselves, so you could hide entire page with a single script attached to one of the questions:

Qualtrics.SurveyEngine.addOnload(function() {
  jQuery(".Skin").hide();
  this.clickNextButton();
});
