Random balance experimental design has been used in industrial applications of statistical methods since 1956. The purpose of this report is to record and discuss in specific form key points regarding this technique. This report will be divided into several parts that are essentially separate. The topics to be covered include the following: 1. Random design and the motivations for use of random designs in industrial, engineering and research activities.2. Techniques for analysis of random data and the apparent application domains for which each technique is appropriate.3. Fundamental problems of statistical analysis that are of critical importance in some random balance applications.
F. E. Satterthwaite (1959) studied this question.
