This method aims to research a certain population, use research instruments in collecting data, analyzing data, with the aim of testing the hypothesis that has been determined. The first prerequisite test carried out is the normality test. This test was carried out to find out whether the research data was normally distributed. Normality test using the Shapiro Wilk formula with the help of the IBM SPSS Statistics application. The conclusion of the influence of interest in learning on the mathematical reasoning abilities of class VIII A students at SMP Bopkri 5 Yogyakarta, the author would like to convey suggestions to parties related to this research with the hope that it will be useful in the future. The results of the research analysis show that there is a significant influence between interest in learning on the mathematical reasoning abilities of class VIII A students at SMP Bopkri 5 Yogyakarta, amounting to 47.7%.]]>
