A Type VI error results from inconsistency between the researchers' question of interest and the statistical procedures employed to analyze the data. An example of a research problem is analyzed to show the increase in statistical power resulting from improved research design, using multiple regression instead of analysis of variance. (CTM)

This study was designed to test the hypothesis that students who are given common errors matched with correct performance as part of their instruction in carrying out a procedure will perform better than students who are given only the correct performance.
