There are many steps in the test development process. The most important step in this process is to determine the validity and reliability of the test. When determining the error of the material is an important concept for the validity and reliability of the test. In order for a substance to be side by side, it must contain the Changing Substance Function. However, only the presence of DMF does not make the substance favorable. The difference in the answers given to the subject is a situation that should be when the difference in the level of abilities of the subgroups occurs. It is not correct to interpret this as a mistake. If a test is done on a heterogeneous population, the analysis of the error becomes the most important component of the measurement process. The most important goal here is to make fair, sensitive and sensitive measurements for respondents. In this study, the theory of probability of third and fourth-class students in the Department of Statistics and Computer Sciences of the Black Sea Technical University has measured the literature levels. Third and fourth grade students were given a 10th material literary test. According to the students’ answers, the gender and class level analysis was carried out. When doing the DMF analysis, Raju's Field Measurement and Lord's Statistics were used. Analysis is done using the R software. Specialist opinion for substances containing DMF has been requested. According to the results of the analysis, some test substances were found to be favorable according to gender and class levels.
