The starRating function adds ratings descriptions (e.g, Very Poor, Poor, Average, Good, Excellent) to a Stars Rating question.

Functionality includes:

• Displays rating description interactively (i.e., on hover)
• Works with any number of stars
• Supports both full star and half-star ratings
• Flexible and translation-friendly specification of ratings labels

Here is a quick video demonstration:

This function is available for a reasonable fee. Contact TomG on the Qualtrics Community to learn more.

Add the starRating function to the survey header to make it available to any question in the survey. Go to Look & Feel → General → Header edit → and paste the provided starRating function JS:

<script>/*Paste starRating function JS here*/</script>

Alternatively, paste the starRating function JS into a question's JS outside the existing Qualtrics functions to make it available to questions on the page.

• Slider type: Stars
• Star interaction: Discrete or Half Step

Add JS to call the starRating function to apply it to the Slider question as follows:

Qualtrics.SurveyEngine.addOnload(function() {
	starRating(this);
});

To change the default options, specify the desired options as an object. For example:

Qualtrics.SurveyEngine.addOnload(function() {
	starRating(this,{ratings:"starRatings"});
});

ratings is used to specify the rating descriptions (aka labels). It is either an array or a string. If ratings is an array, it contains the rating label text strings. If ratings is a string, it specifies the html class of a hidden, unordered list in the question text that contains the rating labels. For example:

<ul style="display:none" class="starRatings">
  <li>Very Poor</li>
  <li>Poor</li>
  <li>Average</li>
  <li>Good</li>
  <li>Excellent</li>
</ul>

The number of ratings labels must be appropriate for the number of stars. If the number of stars is n and the star interaction is Discrete, the number of rating labels must be n or n+1. If the number of ratings labels is n+1, the first string will be displayed when zero stars are selected. If star interaction is Half Step, the number of rating labels must be n*2 or (n*2)+1.

Default: ["Very Poor","Poor","Average","Good","Excellent"]
