One of the most important component that should be examined in determining the quality of a multiple choice itemis the power of distractors. If the distractors of a item are strong, performance of that item in the test is high. Besides,it is also important that the distractors do not contain any information about the correct answer. In a measurement toolprepared with quality items it is necessary to investigate why subjects check the distractors. Incorrect answer options,ie distractors, are not included in the calculation when estimating item statistics. The power of these wrong answeroptions, which are not taken into account when analyzing the distractor, is being investigated. Thus, it is possibleto have an idea about how a item works in the measurement tool. In this study, a distractor analysis was performedfor the items in the Statistical Literacy Test applied to the students of the Econometrics Department of the Facultyof Economics and Administrative Sciences of Karadeniz Technical University. R software was used for the analysis.According to the results obtained from the analysis based on the data obtained, the inter-test performance of each itemwas compared.
