Albert A. Avanesyan , P.E., P.L.S.
Course Outline
This 4 PDH hour online course discusses the errors of measurements that occur in data collection of the actual measurements in different fields of engineering, mapping, land surveying, material sciences, scientific researches etc. It is important to have an understanding of the properties and quantitative influence of unavoidable errors on the final results of any measurements in order to be able to predict the quality of final results of the measurements. This course will enable the attendee to have better understanding of measurement errors and enable them determine an actual accuracy of the given measurements.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
Learning Objective
At the conclusion of this course, the student will:
- Be able to understand different factors that influence accuracy of the measurements;
- Get familiar with different types of measurement errors;
- Be able to analyze results of the measurements;
- Be able to predetermine an accuracy of the calculated function with indefinite number of measured arguments; and
- Be able to relatively easy practically apply theory of measurement errors in everyday measurement activities with deep understanding the application procedure.
Intended Audience
This course is intended for civil, structural, mechanical, chemical, electrical, mining, industrial engineers, land surveyors.
Benefit for Attendee
Attendee of this course will be able to:
- analyze measurements that have already been made for comparison with other results or with specification requirements
- establish procedures and specifications in order that the required results can be obtained
Course Introduction
Human perception of the surrounding is going through the sensations experienced by our senses. When trying to estimate a distance we can easily misestimate a distance by 10% of its value (if distance is small), and by larger error (if distance is long). Same is true for the weight, temperature, humidity, etc. We normally cannot feel atmospheric pressure and we do not have the ability to feel electro-magnetic fields and radio signals.
In order to have the ability to accurately measure, different instruments, tools, and complicated devices are utilized.
However, all of these instruments, tools and devices designed and manufactured employ modern high precision technologies which are not perfect. Any measurements taken with such devices will have errors. True value of the measured value (a particular quantity, property, or condition) is hidden in most cases.
Therefore the question of lowering and eliminating influence of errors on the results of the measurements is highly significant.

Course Summary
Engineers, surveyors should be aware of the errors of the measured data, understand how they will influence results of the measurements so that proper precautions can be taken during final analysis for determination of quality of the data, and consideration of the data for future use.
Quiz
Once you finish studying the above course content, you need to take a quiz to obtain the PDH credits.
