Lecture 3


Summary

The video provides an overview of various experimental designs such as one-factor complete randomized design, factorial design, and central composite design, among others. It discusses the objectives of experimental design, including comparative, response surface, optimum response, and mixture objectives. A detailed example is presented where an engineer studies radar scope target detection methods by manipulating controllable factors like background noise and filtering types, while discussing treatment combinations, replications, randomization, and data analysis techniques.
