[solved] Graphic rating scale

Andrea_sct

Hi,
I am an Italian master student; for my final work I need to create a questionnaire with a graphic rating scale:
simply a line on which one marks an X anywhere between the extremes (fig. below). I have already red the tutorial for questionnaire creation but I haven't been able to find a way to build a graphic scale or find another way to solve the problem (for example a series of horizontal buttons). Have you any solution for this problem?

Hi,

Did you take a look at the slider plug-in? This provides exactly the kind of functionality you are talking about.

To install the plug-in, simply click on the link above, then click on the Download ZIP button. After downloading, unzip the archive and copy the folder called slider to the plug-ins folder (see here) of your OpenSesame installation.

Good luck!

Thank you very much!

Hi,
I have a second question.
I tried to run the questionnaire on a tablet (samsung GT-P7500 Android 4.0.4) but when I start the experiment the app crashes. I read some thread in the forum; could it be a problem of compatibility between the app and the slider? Is there any way to solve the problem?

Hi Andrea,

The slider plug-in is not available in the OpenSesame runtime for Android. So you will need to use an inline_script to implement the slider functionality, instead of using the plug-in. This is a bit inconvenient, but not as difficult as you may think. The following (pretty old) discussion will help you get started:

Hi Sebastiaan,
unfortunately it crashes in the same way, I tried to create a new experiment (droid back_end) with

• only the inline_script;
• the loop containing the inline_script;
• the loop containing the sequence containing the inline_sript;
  but nothing happened the experiment start, I save the subject number and so it crash.
  I tried to run the experiment on my pc with the xpyriment back end. It runs normally, but I haven't been able to insert the questions variable to change item text. Furthermore I don't know how to save the answer with the logger item.

Thanks,
Andrea

Hi Andrea,

What's the error that you see in the debug output when running on Android?
