Procedures are described for determining the statistical significance of a set of ratings made on bidirectional (B) scales. B and its statistical significance can be determined on samples of items or raters. The statistical significance of a mean of B values can be assessed by applying a normal approximation test.

The Rasch simple logistic model is used to examine the relative item parameter values of a personality inventory with respect to populations cross-classified by sex and country. While items conform to the model within each of the populations, half the items show significant discrepancies among the populations. (Author/RL)

The validity of an examination of knowledge in the medical sciences was assessed. Scores in clinical medicine categories and total score of the Quarterly Profile Examination were correlated with corresponding scores on the Part II examination of the National Board of Medical Examiners for three different examination dates.

Ryan is useful, although inadequate and probably pointless. Statistical significance testing appears to be here to stay despite the charge that it is of "marginal scientific value." (SLD)
