Based on empirical data, student learning outcomes on statistical material are not in accordance with the expectations of teachers so it is necessary to apply the Contextual Teaching and Learning (CTL) approach. A CTL implementation can help students to understand concepts and skilled resolve issues. The research purpose is to see whether the students learning outcomes on statistics materials that are taught using the CLT approach are better than conventional approaches. The methods used are experimental studies and the data will be obtained from the pre-test and post-test learning outcomes. The population are the entire class IX student while samples taken by random sampling techniques, two classes, namely as an experimental class and control. Research design is a Non-equivalent Control Group Design. Based on the results with two average difference tests on T-Test statistics were obtained that student learning outcomes in experimental class is higher than the controls. This means learning by applying the CTL approach can improve learning outcomes and the benefits for mathematics teachers gained insight into the CTL learning process.
