摘要:

The analysis of means is an alternative to the analysis of variance for experimental designs with factors at fixed levels. It is especially recommended for ease of interpretation and graphical presentation of results. This paper gives a step-by-step introduction to the use of the analysis of means. The procedure is applied to one-way and two-way factorial designs. Examples illustrating its usefulness for analyzing proportions and counts are also given.

摘要:

The late Dr. Ellis R. Ott has erected his own memorial by providing quality control practitioners with a useful tool for the direct graphical comparison of means. This paper discusses the application of his technique to the first processing step in semiconductor manufacturing. In particular, a simple dichotomous parameter is selected for analysis to demonstrate that significant gains can be realized when this appealing statistical procedure is coupled with quality team involvement.

摘要:

Tables of sample sizes for the analysis of means necessary for detecting differences amongktreatments when two of the treatment means differ by at least a specified amountΔ(measured in units of the process standard deviation) for fixed level of significanceαand fixed powerPare given forα= 0.1, 0.05, 0.01P= 0.5, 0.6, 0.7, 0.75, 0.8, 0.9, 0.95, 0.99Δ= 1, 1.25, 1.5, 1.75, 2, 2.5, 3k= 3(1)20, 24, 30, 40, 60.A comparison of these sample sizes with previously published sample sizes for the analysis of variance does not reveal any substantial differences. Examples of the use of the tables are given.

摘要:

Exact critical values are given for the analysis of means of equal sample sizes for significance levels 0.10, 0.05, 0.01 and 0.001; number of meanskequal to 3(1)20; and degrees of freedom equal tok(1)20, 24, 30, 40, 60, 120 and∞. An approximate analysis for means of unequal sample sizes is discussed and exemplified. Approximations for the critical values are given and their derivation is discussed.

摘要:

A FORTRAN computer program is presented that produces analysis of means plots of the fixed effects for either fixed or mixed models. Exact critical points are used for main effects, and improved decision lines are used for interaction effects. In addition, the program provides an analysis of variance table complete with expected mean squares,Fratios, and descriptive levels of significance.
