Abstract

This study aims to produce a statistical thinking test instrument that is valid, reliable, and feasible to use for SMK Permata 1 & 2 Bogor students. The instrument was developed through the ADDIE model involving the stages of analysis, design, development, implementation, and evaluation. This instrument is declared valid, reliable, and has adequate variations in difficulty levels and discrimination power. All test items are proven valid, with the r count value greater than r_table indicating that this instrument is able to measure what should be measured. The reliability of the instrument is also high in the first school with a coefficient of 0.774 and the second school with a coefficient value of 0.753, the average of both schools with a coefficient of 0.762, indicating measurement consistency. The level of difficulty in both schools shows that the questions vary, with most questions classified as difficult and one question classified as easy. The discrimination power of the questions in both schools is positive, indicating that each question is able to distinguish students' abilities well. Overall, this instrument is effective and feasible to use to measure students' statistical thinking abilities.
