  • simple comparative experiment;
  • good experimental designs, precise estimation - one or more unknown quantities of interest;
  • best ways, allocating new experimental tests - treatment combination, highest prediction variance;
  • best or optimal test plan;
  • textbook on tailor-made design of experiments - a case-study approach;
  • modern, computer-based experimental design techniques - handling real-world problems;
  • sample variance, meaning differences - for different sample sizes;
  • balanced designs, for one experimental factor - two levels, optimal if all the runs, cost the same;
  • error variances, when different for two treatments - balanced design, being no longer the best;
  • experimenter, allocating more runs - to treatment combinations, if uncertainty is larger


This chapter contains sections titled:

  • Key concepts

  • The setup of a comparative experiment

  • Summary
