Units of measurement

the “father” of the International System of Units because he proposed the idea of the decimal system of measurement in 1670. The decimal system was an easy concept to comprehend, and throughout many years scientists would revise his work and make it better. During the French Revolution in 1790, the National Assembly of France requested the French Academy of Sciences to create a new system of measurements that would form a base standard for all measurements. The academy used Mouton’s ideas for…

All of you have experienced unit of measure (UOM) issues in your location and as you know much time is spent correcting and explaining the problems. The other day a location outside our district created a $12,000,000 dollar difference, and as you can imagine several eyebrows were raised as the problem created a huge difference in the company numbers. The importance of UOM accuracy is critical when entering sales orders, creating purchase orders to vendors, and processing vendor invoices. All…

business insider America is the world’s 10th most prosperous nation. Consequently, why should America compromise their success by sticking with an unconventional system of measurement? It is for this and many other reasons why the U.S.A should convert to the metric system. The metric system is a multinational unit of measurement in both the real world and the science field. It is not only renowned but also easier to use overall. Ultimately, the time for the metric system has finally come for the…

A system called CWEED, which measures energy in Ontario and it can "provides solar global measurements as the total of direct and diffuse radiant energy received by a pyranometer." (Hoicka, Rowlands,2011). Therefore, an efficient system can determine whether citizens have easy access to reliable energy or not. However, in some developing countries…

Questionnaire-related Measurement Error Questionnaire- related measurement error could have occurred in a couple questions within our survey because of the way that the questions were worded and the possible answers that were listed. One of the questions where this occurred was in question 8 that asks, “Should the U.S. immigration laws be made stricter, looser, stay about the same, or are you uncertain?” This represents a questionnaire- related measurement error because this question does not…

and blew through the end that was capped by the finger. The free floating bubbles were allowed to descend to the ground where their diameter was measured by a ruler. We found the averages by adding both the measurements of each solution in each test and dividing them by the number of measurements, two. For example: 1.25+1.30+1.20=3.75/3=1.25 average. There were multiple steps taken to prepare our data taken for analysis. Throughout our study, we took observations on the solutions and their…

Standardized Testing Is a Flawed Measurement Standardize testing fails at its one and only job. The ACT and SAT are standardized test, which are taking by high schooler’s as a requirement for college acceptance. Chiefly, the testing evaluates the primary subjects, including math, science, reading and writing. However, the testing material is fashioned by the financially-driven testing business, that is a multi-billion-dollar industry. No surprisingly, the testing industry charges…

meaning of, and relationship between, “reliability” and “validity” ? • Reliability is the extent to which a measuring tool gives consistent results. Reliable means to be consistently accurate, also describes as the absence of random error during measurement. There are three types of reliability: items of reliability, stability, and interobserver. • Validity is the extent to which a measuring tool measures what is supposed to measure. The process of validation includes verifying evidence…

Purpose The purpose of the lab is to design an experiment to verify the spring constant for an unknown spring, also known as k, how much a spring resists change (compression or expansion). We used a method changing a mass and measured the change in x.

ASTM STANDARDS Short introduction – ASTM standards are consensus standards for systems, services, materials and products. ‘ASTM International’ is one of the largest voluntary standard developing organization in the world. It is a non-profit organization that provides a forum for the development and publication of international voluntary standards. There are approximately 12,575 ASTM standards that operate globally. TESTING ASTM STANDARDS- Scope- There test methods help in the determining of…
