On making progress in communication science

This essay advances practices for designing, analyzing, and reporting communication research. The arguments presented center around improving researchers' abilities to cumulate results across studies, but also apply to improving the utility of the individual study. Practices advocated include: (a) sophistication, falsification, and replication as important criteria for evaluating research design; (b) diminishing the importance of the null hypothesis statistical significance test, employing confidence intervals, and correcting correlations for both measurement error and range restriction when analyzing data; and (c) including both descriptive statistics and measures of the strength of bivariate relationships when reporting results.
