The theoretical basis for the Analysis of Means Technique is discussed. In addition, a simplified working procedure is outlined, step-by-step for an actual problem. The data for the problem are analyzed by the analysis of means techniques, which compares differences between means instead of population variances estimates. The data are also analyzed by the analysis of variance technique. The conclusions reached by both techniques are the same. The graphical representation of the ANOM is helpful in understanding data. The ANOM technique is usually used in conjunction with the analysis of variance, either as an initial analysis of data or to augment the analysis of variance.

A new generation of grey literature: The impact of advanced information technologies

A basic challenge of the Weinberg Report addressed the question of information overload. The Weinberg Panel was extremely concerned with the proliferation of scientific literature and the specific issue of how to sift through reams of data to find the “gems” of wisdom, or that which is truly new and useful. In the early 1960s when the report was being written, computers were not part of the information access and retrieval infrastructure. Writing twenty-five years later, in 1988, Dr. Weinberg recognized that the panel had not adequately taken into account the impact of the computer and the growth of the information industry. Today we have a new world of microcomputers and networked information which is fundamentally shifting the paradigm of scientific communication. We have new capabilities, including electronic publishing, visualization techniques, even virtual reality. Without getting into a great debate about the definition of “grey literature,” the main characteristics have traditionally been described as: rapid publication, wariable formats, no public peer review, and no commercial source of general availability. With networked information and multi-media technology, the new world of grey literature is emerging with an interesting set of new and revived challenges. This article looks at the most interesting characteristics, and based on them, presents the thesis that in the 1990s we are facing a new generation of “grey literature”.
