This study investigates the question of whether there is a systematic relationship between the percentage of lexical errors, the percentage of lexical error types and quality of composition.Quality is defined as the score of the composition.The Pearson product-moment correlation coefficient is used to test the null hypothesis of no significant relationship.The study is based on the analysis of 19 compositions of students of Business English at Universidad de La Rioja.All assumptions for the statistical test were found to be met and the correlation coefficient obtained was significant at p<.01 (r = -.78).The results are discussed in terms of how meaningful the relationship and resulting predictions are, and what this may mean to planners of writing courses.
