This paper focuses on the interpretational difficulties that confound polynomial regression analysis. While polynomial regression is statistically sound, it produces awkward equations which "describe" a curve with a series of linear slopes. An example illustrates the technique and the awkward...

Though it has played an important role in sociological inquiry, typological research has been criticized on two major issues. Theorists have been critical of the tendency to reify theoretical concepts by treating them as if they were directly observable; quantitative researchers have been...

Using randomly generated samples from populations having varying rhos, different shapes of distributions, and varying sample sizes, the effects of violating the population normality assumption underlying r were examined. Results indicate that the normality assumption underlying r is robust (i....

The interpretation of experimental manipulations and the precise relation. ship of that interpretation to the observed effects are two major problems facing experimental procedures designed to test social theory. The results of the present study indicate that careful measurement of intervening...
