Second language (L2) research relies heavily and increasingly on ANOVA (analysis of variance)-based results as a means to advance theory and practice. This fact alone should merit some reflection on the utility and value of ANOVA. It is possible that we could use this procedure more appropriately and, as argued here, other analyses such as…

This note proposes an alternative implementation of the regression method which should be slightly faster than the principal components methods for estimating missing data. (RC)

Addresses two related problems: what are the appropriate measures for comparing effects of blocks or compounds of variables (each block conceived as having a single effect) when the causal ordering is assumed to be known, and how can single measures be created for each such block or compound, so that the comparisons can be made.

The relative precision of four methods of estimating missing data in principal components analysis was investigated. Artificial data with known characteristics, obtained from Cattell's "Plasmode: 30-10-4-2," was used with one third of the data on half of the variables being systematically eliminated. The four methods of missing data estimation…

This paper comments on the impact of computers on statistical analysis and presents a concise, nontechnical overview of five statistical methods now being applied in educational research. Appropriate uses of these techniques are pointed out, along with dangers concerning misapplications. (PP)

Conclusions one would make from looking at average faculty salaries in a specific department were compared with those conclusions evolving from a regression analysis of the same salaries. The standard salary study does little more than report the average salary associated with each faculty rank within each department, while a regression study…
