Accuracy and precision

the use of precise amounts in financial statement elements that cannot be precisely determined. Therefore the amounts are subjective and lack precision because they are plagued by the use of subjective management foresight to determine the values utilized in the financial reports. Where the use of estimates is encouraged there is definitely a lack of accuracy and reliability of the financial information provided (Lev 2016). Some of the typical examples (Table I) of accounting estimates…

Fig. 1.1 Schematic principle of Electro Chemical Machining (ECM) 1.2 Principle of ECM Electrochemical machining removes material from the work piece by electrochemical process. The working principle is anodic dissolution in which the work piece as anode and the tool as cathode. Both electrodes are immersed in the electrolyte and electrical applied to these electrodes. The electric conduction is achieved through the movements of ions between the anode and cathode through the electrolyte. The…

based on the results, but there were two flaws in our study. The hypothesis was definitely supported by our data and I am fairly confident in the results. Although I am fairly confident in our results, there are two sources of error that limits the accuracy of the hypothesis. The two major sources of error in our study were the sample and the fact that all the answers were yes/no. The sample was all college students from the same college which obviously do not accurately display society as and…

The atomic bomb was and is still today the most destructive weapon in history. When detonated it a spray up a giant mushroom cloud of soot and ashes that would gloom upon the city below. World War II was one of the most destructive and costliest wars in history. The war lasted six years, and over sixty million people, both military and civilians, lost their lives. As the war raged on, the Allies and the Axis Powers sought to develop better technologies to gain the advantage. Both sides…

Abstract The purpose of this experiment is to determine the relationship between the temperature and pressure of air at constant volume which placed the Jolly’s bulb in water of different temperature. At the constant volume of the air in the Jolly’s bulb, the temperature and pressure of the air are measured and recorded throughout the experiment. The result shows that the pressure of the air in the Jolly’s bulb increases as the temperature rises, and the pressure decreases as the temperature…

The final part to this study is the rationale for using out-of-level testing. There are three main themes to this sections. The first is, overly difficult tests promote increased guessing and student frustration, which reduced the accuracy of the test results. The basic question is whether students who score low on grade level tests would score higher on lower level of the same test. To answer this question much of the research on out-of-level testing has examined the effects on raw scored and…

INTRODUCTION Trypsin is a proteolytic enzyme, important for the digestion of proteins. Enzymes are biological catalysts for metabolic process in cells. A catalyst is a substance that changes the rate of a reaction. Enzymes act as catalysts for chemical reactions in the body. Enzymes are large proteins that are not consumed or changed in a chemical reaction. They are highly specific to the substrate - the substance an enzyme acts on - they act upon. When an enzyme is available with an empty…

Determining the effect of the mass on the drop time of a parachute Introduction and hypothesis The drop time of a parachute is dependent on multiple factors. Apart from mass, there is the obvious height, area of the parachute and other external factors such as wind. Mass is one of the main effectors of the drop time of a parachute, which can be proven through Newton’s second law, F=ma (Force=mass*acceleration). Rearranged, this gives a=F/m, where acceleration can also be gravity, if falling down…

There are few things that are more disappointing for athletes and fans than witnessing their favorite sports team losing a game that was decided by a bad call. Implementing the use of instant replay would allow for an increased accuracy and make sure that missed calls are corrected. Even a good official could find him or herself out of position and be unable to see how a particular play unfolds, or they could simply just miss a call. Instant replay could be the answer that can help fix the…
