![]() The results showed an increase in cycle I to cycle II for the level of activity reaching 42.86% and completeness of learning outcomes reached 55.53%. Data Analysis Techniques with comparative descriptive techniques and interactive analysis techniques. Data collection techniques through: 1) observation, 2) questionnaire and 3) test. The research method uses Classroom Action Research with 3 cycles. 2) Describe the changes in mathematics learning activities and statistics material, after applying the STAD learning model to students of XII.MIPA 7 SMA 2 Kudus semester 1 of 2018/2019 academic year. This class action research aims: 1) Determine the magnitude of the increase in mathematics activity and learning outcomes in statistical material, using the STAD learning model in class XII.MIPA 7 students of SMA 2 Kudus for semester 1 of 2018/2019 academic year. Lower group students are less able to understand the problem, but can To plan solutions appropriately, able to implement The completion of what is planned, but underprivileged to Look back at results and processes.STAD LEARNING MODEL TO IMPROVE ABILITY TO SOLVE STATISTICAL PROBLEMS IN STUDENTS IN CLASS XII MIPA 7 SMA 2 KUDUS 2 YEARS LESSON 2018/. Group students are less able to understand the problem, but are able to plan Properly, able to implement settlement plans in accordance with the Planned, and able to look back at the results and process. Settlement appropriately, able to implement the plan of completion according to what Are planned, and are able to look back at results and processes. The group's students are able to understand the problem well, able to plan Subjects were chosen taking into consideration the teacher's explanation of students ' ability to solve problems. This study aims to test the problem solving skills of grade XII students SMA in learning. One of the efforts to improve the learning process is to choose the right and innovative learning model in mathematics learning, with the steps to give practice about the problem-math problems in the statistics material found in the UN can help in solving problems when the UN progresses. This means that the percentage of students who are able to solve the problem with the correct strategy and procedure is still slightly compared to the percentage of students who solve the problem using the formula. The results of student research are able to solve problems that are complicated and able to formulate, and communicate their findings. Problem solving capability is one of the main focus central In mathematical learning. ![]()
