All measurement has a limit of precision and accuracy, and this must be taken into account when evaluating experimental results. This course focuses on the fundamental principles of measurement and uncertainty. Topics include the international system of units, statistical description of data, representation of experimental error, data analysis, sensor application, and case study of measurement system.
At the end of this course, students will be able to
1) Explain the International System of Units.
2) Have an understanding of the basic concepts of probability, random variables, probability distribution, and joint probability distribution.
3) Explain the fundamental principles of measurement and uncertainty.
4) Have an understanding how measurement systems are designed, calibrated, characterized, and analyzed.

|✔ Specialist skills||Intercultural skills||Communication skills||Critical thinking skills||✔ Practical and/or problem-solving skills|
At the beginning of each class, solutions to exercise problems assigned during the previous class are reviewed. Towards the end of class, students are given exercise problems related to what is taught on that day to solve.
