## Enormously Valuable Course!

5Richard,

In addition to working with you as our uncertainty budget consultant, our firm wanted to take advantage of your class. As I moved through the course, I realized most of the questions I’d either asked or planned on asking are covered in your course. I find the instruction on the process to be enormously valuable, but I’m still glad I hired you to do our budgets!

Thank you for your intellect and the ability to transfer a portion of your knowledge.

Best regards,

## Through lesson and helpful instructor

5I find this course very interesting for absolute beginners and quite easy to follow. There are times when it seems to be confusing especially when the lesson/assignments are not the same as your parameters, but emailing Rick will help you get back on track.

## Best and Clear Uncertainty Training

5The course makes us to clearly understand the measurement of uncertainty from the basics with very clear explanations with valuable reasons, suggestions and clarifications. Videos and Assignments changed me from a doubtful person to a confident man.

The complete course material was available on the first day of the training. Helped to go through the entire course content.

I strongly recommend the course to all who are really interested to know, to learn and do measurement uncertainty.

## Best Uncertainty Training Around

5Being exposed to the calibration and measurement industry as long as I have, I have NEVER had a training course cover as much detail as this. Rick is always more than willing to help answer any questions you may have about anything – even if it’s not specifically referenced in his course. The examples are well placed, the course content in clear and concise, and it can be completed online in your own time! I never thought I’d get as far as I did, but I’m now able to confidently create uncertainty budgets to assist my company with 17025 compliance, and it’s a great feeling. 5 stars to you, Rick – I can’t thank you enough for all of your help.

## This course deserves more than 5 stars

5I have spent a monumental amount of time researching measurement uncertainty. There are many resources available online. However, the issue is that you will rarely find any two sources that agree on everything regarding measurement uncertainties. This makes researching measurement uncertainties on your own overwhelmingly confusing and extremely ineffective.

I have always excelled at math. I took four advanced math courses in high school just to avoid taking a foreign language. I was a nuclear reactor operator in the United States Navy. Yet, the process of calculating measurement uncertainties has always eluded me.

That is, until I enrolled in the measurement uncertainty class offered at isobudgets.com. This course is BY FAR the best measurement uncertainty course available. The courses are very well put together and organized. The instructor is very knowledgeable, helpful, and responsive.

When I first read the GUM, it was basically useless to me and none of it made sense because I did not understand the math involved. I now have a much deeper understanding of the math and fundamentals behind uncertainty calculations, and that is entirely because of the training course from isobudgets.com.

I absolutely recommend this course to all who consider themselves calibration and metrology professionals.

5The course was definitely useful. I feel beter prepared now to assess uncertainty for the different methods used in our lab and more in control of the uncertainty parameters.

5This course looks really good based on the intro material.

5This is a great course for anyone wanting a detailed understanding of calculating measurement uncertainty! Thank you ISO Budgets!

5Excellent course for understanding the steps to create and evaluate CMC’s for labs. Response to questions is timely and helpful.

5Great Course. The content and delivery style are easy to follow.

My biggest takeaways was the acquired confidence in calculating measurement uncertainty.

I have ended the course feeling motivated to whip out my new skills and go on a new budget adventure.

Recommending this course wholeheartedly.

5The course is very informative. All of the assignments are worked through by the instructor to help show the interaction of each calculation. I would highly recommend this course to anyone working in a calibration laboratory.

5Working through this course was a very positive experience – the instructor is responsive, willing to answer questions, and provides feedback on each assignment. It is immediately obvious that a great deal of time and effort has been put in to structuring the course and putting together supplemental materials to assist students. I finished with, what I feel, is a very strong foundation and understanding of what makes an uncertainty budget and how to collect the information necessary to develop more.

The lessons are broken up in meaningful ways and the progression feels appropriate. A wide variety of examples are demonstrated, and in more ways than one – the instructor provides demonstrations of how to perform calculations and collect information in corresponding assignment videos and literature for each lesson. References and useful tips are included to help the student identify how the uncertainty budget they create compares to national labs and other accredited bodies.

5Creating an uncertainty budget from start to finish can be an intimidating challenge. Mr. Hogan has created a systematic, step by step approach that breaks the process down into easier to understand concepts. Each lesson is clear and concise, with excellent examples and tools that walk the student through the process of building an uncertainty budget. I highly recommend the course.

5Five Stars !!!

5Mr Hogan has tremendous knowledge and insight to the industry as a whole and makes Measurement Uncertainty Applications in an easy to understand process.

5Great Information, and help every step of the way. I now feel I am ready to start calculating MU.

5“Great course. Mr. Hogan takes the mystery out of the application of measurement uncertainty and the application of it. I highly recommend this course to everyone.”

5The course was well taught by Richard, he did a great job of watering down the confusing points to point out what they really are looking for in those section. The course helped clear up a lot of things for me and I will be strongly recommending to others who are interested. I really enjoyed how this course was taught and how the schedule went. Richard is also very easy to get in touch with to ask any questions.

5This was a great course

It’s full of good examples and tips to find information.

Secrets to evaluate and reduce your uncertainties.

And the way that Richard coaches you makes this course an excellent invest.

Congratulations Richard.

5A good introductory course to measurement of uncertainty.

5A very good intro to measurement uncertainty. Rich’s lessons and projects do a great job of summarizing the techniques of estimating uncertainties related to factors not typically considered. The course provides a valuable calculator to use going forward and Rich does a great job walking through all of the aspects of using it. Rich is also very responsive to questions and will communicate regularly if prompted. I personally would have liked some more real world examples beyond the direct teaching points for a few of the concepts, but overall an excellent hands-on experience. 5 stars.

5The course presented detail material using simple terms. The project work in Excel kept the participant engaged while reinforcing the lessons. The overall summary at Lesson 9 tied the elements back together in context. The last lessons guided the participant on practical application of the calculations and presentation of the information that was developed during the course. Well Done!

5Great course with a lot of information given, very easy to follow along with and went at a good pace with lessons and projects.

5Very thorough, clear and concise. Great detail and examples are very helpful. Highly recommend *****

5This course is accessible to students and thorough. Mr. Hogan explains the calculations well as he walks the students from the introductory concepts of uncertainty to the completion of an uncertainty budget ready for submission for ISO 17025 approval. I greatly appreciated his focus on developing a robust uncertainty budget that was defensible to auditors, and on many occasions pointing out common problem areas that assessors flag. The documentation is first rate and will provide a valuable reference.

5A thorough, comprehensive and user-friendly course on calculating measurement uncertainty. This ISO Budgets course not only provides you with all the tools you need to calculate MU and compose CMC Budgets, but also references numerous sources of additional guidance. Richard Hogan has provided a solid MU course with materials you will continue to utilize going forward.

5Course was very informative. Very helpful.

## How to Calculate Measurement Uncertainty for ISO/IEC 17025 (Advanced)

5This class was very in depth and insightful as to the uncertainties in calibration. For someone without a high level of math, Richard explained it well as well as showing how to set it up in excel. It is great to have the excel calculator and access to the video’s after completing the course to go back when needed.

Richard runs a great program for uncertainties. I would recommend it to anyone who is looking for help in uncertainties for ISO 17025-17.

5Excellent course! I liked the excel calculator as it gives the hands-on experience and can be extended and used in various applications.

## How to Calculate Measurement Uncertainty for ISO/IEC 17025 (Advanced)

5There is a lot of material out there on uncertainty in ISO/IEC 17025 but I found most of it pretty dense, with lots of arcane formulas and poorly-defined terms. I have been using the “Easy Uncertainty Calculator” from Isobudgets for about 9 months and found it to be refreshingly easy to use. I have enough of a statistics and metrology background to figure out most of how the Calculator works and what assumptions it makes, but I wanted to be sure I was on the right track – and this course (How to Calculate Measurement Uncertainty for ISO/IEC 17025 (Advanced)) was a perfect fit. The “Simple Uncertainty Calculator” supplied with the course is a bare-bones version of the Easy Uncertainty Calculator, but the underpinnings appear to be the same (side note: if you find the “Simple” calculator useful at all, get the “Easy” version – it ties a lot of the concepts together automatically). Now I can not only calculate an uncertainty, but I’m confident that I understand where it came from, what contributes to it, and what assumptions are involved. I’d also like to single out one of the new course modules on statements of conformity and decision rules – again, there’s a lot of alleged “guidance” out there but this course focused on clear and practical definitions.

## Helpful

5I had some experience in college with estimating uncertainty but this course really helped take what I learned to the next level.

## Good value and use of time

5Rick is an effective communicator with a wealth of experience in metrology.

I started the course with little or no understanding of statistics and now, between this course and the blog posts that Rick has done, I feel that this is the easy part of the process.

The course is very practical and wastes no time on irrelevant data as it walks you through the process of assembling a thorough uncertainty calculation

Cheers!

## Finally I manage to complete the course

5The course is easy to understand and Rick has hade the presentation clear and has it delivered consisely. The duration for each topic is also suitable as it is not too long.

## Brilliant!

5Excellent course! The structure and content is perfect for anyone who wants to get ISO17025 accreditation. Rick was very responsive with questions that I emailed and always answered accurately and promptly.

## Now I understand the meaning of unsertenty calculation

4A very good course even if it some times was hard to understand all the formulas and examples, especally in lesson 10-14.

I think I have a very good understanding to make an uncertenty budget and all the extra informations (guides) will be well used further on.

It is great to be able to use the lectures for some time so I can be guided by you during my own calulations further on.

5Everything in this course is very useful and helpful. Glad I was able to take it.

5This was a very helpful course! It was well structured and very informative. Highly recommend.

## Very informative

5As I haven’t performed uncertainty before, this course is easy to follow and simple in its explanations. I love the way that the work sheets are talked through step by step.

## State of the art Measurement Uncertainty course

5This course by Rick Hogan has made me a real expert in measurement uncertainty. I am now able to teach my colleagues at work and guide them towards making our in-house torque calibration laboratory meet the measurement uncertainty requirements of the ISO/IEC 17025:2017 standard. I am now very confident of attaining accreditation for our torque calibration lab. I have really appreciated the practical approach in taking this course. I highly recommend this course to anyone who wants to be an expert in measurement uncertainty and laboratory accreditation.

## Good information.
