Comparative judgement methods are used by social scientists to construct reliable measurement scales that are difficult to construct using traditional methods. Such scales typically measure important but nebulous theoretical ideas such as ‘beauty’ or ‘writing quality’. Comparative judgement involves no coding schemes and no categorisation; instead judges make holistic decisions about which of two presented objects better represents the theoretical idea of interest. Comparative judgement methods have a long history but are only now gaining traction due to technological developments making them more accessible to researchers. The course will take attendees through the entire process of using comparative judgement to construct reliable measurement scales.

The course covers:

  • The background and theory of comparative judgement
  • How to choose suitable objects and judges
  • How to design and run a comparative judgement study online
  • How to process and interpret study outcomes
  • How to evaluate reliability and validity

By the end of the course participants will:

  • Know how to run a comparative judgement study using the free NoMoreMarking website
  • Know how to process and interpret comparative judgement outcomes

IMPORTANT: Please note that this course includes computer workshops. Before registering please check that you will be able to access the software noted below. Please bear in mind minimum system requirements to run software and administration restrictions imposed by your institution or employer which may block the installation of software.

  • Access to the website via a computer browser.
  • I will demonstrate and provide code for processing data using R. Installing R prior to the online workshop is helpful but not essential.
