Important announcement

Dear visitor,

Courses and their contents that are currently available the platform will partly be migrated. URL’s for this content will change and content might be unavailable for some time. In addition, some courses will not be available anymore.

If you are linking to specific courses on this platform (for instance for your students), please take timely measures to avoid problems with access. Possible actions are:

  • Download the materials to your local platform (laptop, server)
  • For educators only (including TU Delft lecturers): Contact us at ocw@tudelft.nl and inform us what course you are using in what context (institute, program, period of use, number of students). We will research (in collaboration with the authors of the course) and decide if we will migrate the course, and if yes, can supply you with a new url.

Thank you.

2.7.1 Back to the watermelons

Course subject(s) Module 2. Calibration and Information score

You might consider that it is quite intuitive to evaluate which expert is more informative based on the Dutch eating habits examples.

Well, let’s see!

Consider again the question about the watermelon: What is the percentage of water in watermelon?

Suppose other two experts, Expert C and Expert D provide their assessments.

Expert 5% 50% 95%
Expert C 80 90 99
Expert D 75 95 99

Note how different the information scores are of the two experts when different intrinsic ranges are considered!

It’s good to remember that the larger the intrinsic range, the more informative expert’s assessments can be.
