History of measurement

The most likely source of systematic error is parallax error. It is highly likely that measuring the length of the tube was affected by the positioning of the ruler against the tube as well as the eye against the ruler. The absence of millimetre measurements on the ruler also required the observer to estimate to the nearest millimetre which also likely resulted in inaccuracies. The mouth of the tube was also rigid which has possibly had an effect on the end correction value of 0.4d, however this error is simply an assumption and it is uncertain whether or not it did have an…

Some of the aspects from these three articles can advance the understanding and the validity of Merton’s anomie theory. When looking at the study done by Baumer and Gustafson, the quality of their study is very sound. The researches find a way to measure the different parts of Merton’s theory, such as legitimate employment and other things that would be considered blocked opportunity and crime, and measure them (Baumer & Gustafson, 2007). Baumer and Gustafson also give solid background…

Based on this calculation, would timing more drops help in reducing the uncertainty of the average times? In this experiment would it be feasible to take the optimal number of measurements? In my works, there are at least 5 times of each ball to measurement need. With the calculation, If student timing more drops, it will help in decreasing the uncertainly of the average time. So, 5 times of dropping are enough for this experiment. Q9: Were the times given by the preferred method for the first…

Sources of Measurement Error Measurement is the process by where we assign value to empirical events, objects or properties, or activities according to a set of rules or standards (Cooper & Schindler, 2014). The goal of measurement is to represent the events, objects, properties, or activities with complete precision and control. Because a researcher does not have complete control, errors do occur. Measurement error is the difference between the research value assigned and the true…

As discussed previously there has been various methods developed in the past few decades for performance measurements; however the most acceptable and regarded approach is the "Balanced Scorecard Approach". Balanced Scorecard addresses one major issue that financial measurement tools are insufficient to guide companies for success. It provides a broader sense of indications for the total value creation in organizations through tangible and intangible assets. Balanced Scorecard approach help…

Personality should be valued or construct to get detailed characteristics of a person. As we cannot physically see the traits, there will be a question about is it really there or true? Scientists made some interference about people and how they are like and such measurement are hypothetical most of the times. Smith (2005) was explaining in his study that even though those theoretical theories are there, it is necessary to make sure they are measure “in a convincing, valid way” (P. 396).…

Response Essay: How Measurement Fails Doctors and Teachers This essay will cover the topic of measurement and analytics in the medical and educational sectors and how it is negatively impacting each one respectively. I personally agree with the writer’s viewpoint and feel as though our current methods of measurement in both the healthcare and educational fields are incorrect; with issues and metrics of greater importance being overlooked due to an excessive amount of measurement. However, the…

annealing the sample is to increase the grain size of the sample. The annealing temperature is 300℃, 4 groups of samples will leave in the annealing chamber for 6, 12, 24 and 48 hours. And the annealing must be in Argon or Nitrogen gas atmosphere at 1 atm because the samples will be oxidized in air. XRD XRD is to determine the microstructure of the samples. The structure information can be determined by analyzing the peak of diffraction angle 2θ degree. X-ray diffractometers consist of three…

As students’ learn how to measure, individuals misinterpret the representations. Although it seems like a simple concept for adults, Battista (2006) claims measurement can be a difficult concept for children to understand. A common misconception in measurement is the students’ misreading the scale on a ruler, as they do not know “whether to count the marks or the spaces” (Averill & Harvey, 2010, p. 106), or whether to start from the one or the zero. It is merely a misunderstanding of the meaning…

in at least one of the designs. My partner and I decided to make the glasses super colorful and fun looking. My partner used a variety of fun colors to make the design pop out and draw the eye. We wanted out design to be noticed. Most people look at things that are attractive and not bland, so we made our prototype very eye appealing. I think it would be fairly easy to shelve because it's not a wobbly structure and each design would go right on top of each other. Our prototype has eye appealing…
