|Course description: Course objectives:
The course objective is to acquire theoretical and practical knowledge in the application of statistics in metrology.
Enrolment requirements and required entry competences for the course:
Attending of laboratory exercises (it is possible to abstain from participating in two lab exercises however this abstention must be compensated for) Attending the lectures (three abstentions are permitted) Passing the practical part of the examination. Passing the theoretical part of the examination.
Grading and evaluation of student work over the course of instruction and at a final exam:
Successfully complete the practical part of the examination: 70% Successfully complete the theoretical part of the examination: 30%
Methods of monitoring quality that ensure acquisition of exit competences:
In order to have continuous monitoring of quality performance of the Course an anonymous, simple and quick questionnaires of student"s opinion will be preformed by use of module Moodle application Question. The readiness of students to other forms of engagement will be analyzed (research, discussion, development projects, etc.) At the end, the quality of Course will be assessed through University questionnaire that student fulfills online, through the ISVU system, in order to evaluate work of teachers and the attractiveness of topics.
Upon successful completion of the course, students will be able to (learning outcomes):
Interprete the basic measurement terms with statistical quantities. Use statistical tools and methods for the analysis, comparison and validation of measurement results. Conduct a statistical analysis of the quality of the measurement system. Use statistical tools in the estimation of the process capability. Determine the influence of the measurement system on process capability assessment.
