Measurement

Experiment 2: Aim: In this experiment you will determine the mass of a single drop of water by a graphical method. You will evaluate its uncertainty. Data: Table 1: Number of Drops: Mass of Beaker + drops/g (0.01g) 1 2.36 g 2 2.38 g 3 2.40 g 4 2.44 g 5 2.46 g 6 2.48 g 7 2.50 g Chart 1: Analysis: The mass of 1 drop of water is 0.4g. By taking the total mass and dividing it by the number of drops we can figure out the average mass of a drop of water. However the number of drops should…

The percent error showed scattered results. When looking at the table, the percent errors can go from 7.05% to 200% and the reason for the extremely high percents were systematic errors made while measuring vinegar or other measurements. Two of the three deformities in measurements come consecutively after each other: trial 6 and 7. Although three of the percent errors show the high percent, most stayed below 20% which is still not sufficive but it represents a trend in percent errors. In…

Therefore, they should be considered together for the best result. However, if these factors are considered separately in measurement, reliability is more important that reliability. This is mainly due to the fact that when the measure of an aspect is reliable, it automatically becomes valid. If one gets consistent results then the measurements they get are both reliable and valid. In some cases data collected may be valid but not reliable. In such a case the results are useful in…

quite significant. This is shown through the results table where the first experiment showed a titre of 31.4 and then the next two showing 32.1 and 32.2. The final two measurements are quite similar in scatter and could have easily been a systematic error when determining the end point of the procedure, however the first measurement is so far removed from the others that there was clearly a random error. This clear random error has therefore, corrupted the precision of the…

Measurements and Collection. In order to show the effect of the structured intervention on the outcomes of the mentees, different types of data will be collected and analyzed to detect trends over time between mentoring groups (E-SBM, Traditional BBBS, and Control). Along with demographic data collected upon program entry, data will be collected on multiple measurements corresponding to each hypothesis. - The first intermediate question states: What is the difference in behavior between each…

Which glassware is the most accurate?The least accurate? You can use the percent error to find the accuracy of each glassware, therefore you can compare each glassware to each other. The measurement labs reveals that the beaker produce results closest to the actual value, which means it is the most accurate, while the erlenmeyer flask results revealed it was the least accurate of the three- look at column six "Accuracy(Percent Error)". 2B.Which Glassware had the smallest precision and the…

The stylus system that is categorised in this group is the stylus system of micro CMM, which has a similar design with the conventional CMM probing system. As described in ISO 10360-1, the stylus system has a spherical stylus tip, a rod stylus shaft and a sensing element. These styluses also operate in contact mode. (1.1 until 1.5 have been discussed in progress report 2) 1.1 UMAP Mitutoyo Stylus (1993-1999) Figure 2.1: construction of UMAP stylus system Mitutoyo UMAP stylus system was…

are constantly brought up when politicians campaign for office. We, as a nation, are in a record low unemployment rate of 4.9 percent, but as I will explain in this paper might not be as fortunate if current policies go unchanged. Quantitative Measurement of Unemployment The American Economy could be described as a metaphorical locomotive traveling forward on the rails of monetary infrastructure. On boars there are two kinds of passengers: those who ride without the capabilities or desire…

Although both theories compliment each other TQS is more suited to larger businesses whilst entrepreneurial aspirations focus primarily on smaller firms. An essential part to the implementation of TQS is that companies must have clear objectives in order to be successful in defining quality. These objectives consist of the identification of the customer and the identification of the service manor that needs to be used. Stamatis (1996) rightly explores how this could vary depending on the size…

from making a salad to constructing roller coasters requires the involvement of science. But we as humans have not created a way to completely eradicate the error of a measurement reading. Even with all of the advancements we have made in regard to technology and scientific resources, there is no way of getting an exact measurement. This is extremely apparent when looking at chemistry laboratories. When looking at a 50 mL graduated cylinder for example, each member of the group could gain a…
