A star scale is a type of rating question that allows respondents to rank products and/or services on a point scale, using stars for visualisation.
A respondent can express his/her opinion about a product/service (e.g. movie) using a number of stars when filling out his/her survey.
You can specify the descriptions for the number of stars at the Star choices, e.g. 1 star = Poor, 2 stars = Fair, 3 stars = Average, 4 stars = Good, 5 stars = Excellent.
Using the Add star button, you can add more stars (and star choices) to the point scale. For instance, you may want to use a 10-point scale for a detailed, critical evaluation. For a global evaluation, on the other hand, a 3-point scale (with the descriptions Unsatisfactory, Satisfactory, Good) usually suffices. To reduce the number of star choices, you can click the x symbol behind the corresponding descriptons (see image above).

After the participants have completed the survey, you can view the results of among others this question type in the online report. To do this, you can click the red circled icon in the created basic report, see under Analyze. Click here for a description on how to create a basic report.
As soon as you have clicked the corresponding star scale question in the online report, a chart appears on the left (see below) displaying the rating of the product or service by the total number of participants. The descriptions of the star choices that you have defined can be found in the legend directly below the chart.
From the above chart, you can deduce, for example, that the product (in this case a movie) is considered Excellent by 2 participants, Good by 5 participants, Average by 2 participants and Fair by 1 participant.
When downloading the raw data with question text and answer option labels, the defined star choice descriptions will be displayed in the columns of the Excel file. Both the second and the sixth participant in the above example have rated the corresponding movie (column F) as Excellent.
