This study tested the hypothesis that references to an article in Wikipedia affects the article's citation trends. A measure citation "propensity" was created, which measures the likelihood of an article being cited more than what is to be expected by chance. Using statistics in the Scopus database and this measure, it was found that while the number of citations to an article does increase in number over time, citation propensity does not increase for an article after it is referenced in Wikipedia, meaning that references to an article in Wikipedia does not affect the article's citation trends.
