A test to assess student understanding of measurement and uncertainty has been developed and administered to 90 students of the Faculty of Applied Sciences. The aim is to identify the level of students' understanding of uncertainty in physical measurements. A ten-item-test answered within thirty minutes focuses on three objectives of the study: 1) To identify students' understanding behind multiple measurements and data dispersion, 2) To identify students' ability to carry out numerical calculation of uncertainty for a given set of data and 3) To identify students' understanding of uncertainty propagation and the use of uncertainty for comparison of measurement results. The test was administered by the researcher to degree level students (Bachelor of Science) from three different courses in the faculty: Physics (AS203), Bio-Composite Technology (AS232) and Industrial Physics (AS231).
