This study aimed to improve students' high order thinking skills (HOTS) specifically in Statistics Method I subject by implementing the "what-if" learning strategy. This research is a two-cycle classroom action research. The subjects of this study were as many as 16 students in the 2018/2019 academic year as semester IIA students from the Mathematics Education Study Program, Faculty of Teacher Training and Education, Universitas Mahasaraswati Denpasar. Techniques for collecting data used interviews, observations, and essay tests. This research used two methods for data analysis, i.e. qualitative analysis and quantitative analysis. Qualitative analysis uses methods such as mathematical models and analyses that are performed by conducting explanations restricted to data management techniques. Moreover, the quantitative analysis used a simple level calculation to determine the average value and completeness level of students' high order thinking skills. The study results showed an increase in the students' high order thinking skills from the first cycle to the second cycle. The average score of the students' high order thinking skills only exceeded 71.125 with completeness level 62.5 percent in the first cycle.
