摘要:Balanced Incomplete Block Design is widely used in many of applied problems, such as sensory analysis, market research, comparing products, etc. For this purpose, in this study Balanced Incomplete Block Design is introduced in detailed, and Modified Durbin Rank tests suggested by Best (1993) are given for this design. a numerical example is applied by using real data set for Balanced Incomplete Block Design and sensory fatigueness . The analysis of Modified Durbin Rank tests show that the difference between products is determined at significance level 0.05. Also, by using various Balanced Incomplete Block Design related with smaller data set, the similar results are obtained.
