Clone Evaluation

The Problem

The field reconnaissance team has found 20 new varieties of tomatoes. You have assembled an expert panel that you usually use to evaluate new vegetables before they are introduced into commercial markets. The problem is that your boss has said that some of your past choices for commercialization have not been very successful. He questions whether your panel's preferences match those of the consumers.

You work on the hypothesis that your panel's taste is the same as the general public. You test this by using four of your experts and four randomly chosen consumers. You ask each of these people to rate the 20 new tomato clones by a simple "yes" or "no" regarding the potential for commercialization.

Does the Expert panel represent the preferences of the Consumers who were tested?

Please Note: These are artificial data and they do not represent any real situation.

The Data

The data are structured the following way:

  • Each evaluation used a 1 for "yes" and 0 for "no."
  • The Experts are identified by E1 to E4 and the Consumers are identified by C1 to C4.
  • The data are structured so that they can be copied and pasted into PAST.
    • When you are ready to paste the data into PAST, make sure that both the Edit Mode and Edit Labels boxes are checked.
