Introduction Several instruments are used for determining the mass of a chemical; these instruments are called “balances.” However‚ different balances have different measurements‚ meaning that some balances are more accurate than others. Moreover‚ there are several techniques that are used or practiced in order to obtain an accurate measurement. The two techniques are direct weighing and weighing by difference. Direct weighing simply means to read the mass or value of the mass directly from the balance

A recent report on the weekly news presented the findings of a study on the effectiveness of Onglyza‚ along with diet and exercise‚ for treating diabetes. According to Bennett (2009)‚ a population is defined as “the complete set of people or things being studied” in a statistical study. Given that the information is in relation to finding the success of a drug used to care for

chemicals together. Accuracy is the magnitude in which a certain measurement agrees with the standard worth for that measurement (Dictionary‚ 2011). Precision is how close the measured standards are to each other (Math is fun‚ 2011). Society depends on accuracy and precision in everyday life. These two relationships are often substituted freely‚ but both have crucial differences. Businesses entail both accurate and precise measurements to stay in business. Accuracy states that something is constant

Contents Figures Abstract An experiment was designed and conducted to confirm Archimedes’ theory which states that an object will float in water providing its mass is equal to or less than the volume of water it displaces. The second objective of the experiment was to produce a value for water density. It was expected that when additional mass was added to a floating vessel‚ it would displace more fluid and the increasing submerged volume of water could be measured‚ and a value for water

that does not involve mathematical models (Wikipedia‚ 2015). GCSE Science (2014) states that accuracy is the degree of closeness a measurement of a quantity is to that quantity’s actual value. With quantitative methods‚ accuracy defines the limits of the errors. Ideally‚ a piece of apparatus (e.g. a burette in a titration) is both accurate and precise‚ with measurements generated close to the true value. To ensure accuracy in quantitative methods‚ apparatus must be calibrated‚ checked and analysed

inclined forces are applied to the truss‚ thereby simulating various load cases. The occurring tensile and compressive forces in the bars are recorded by means of strain gauges. Computerised evaluation is provided by measurement amplifier FL 151. The software is used to manage the measurement data and provide graphical representation of the bar forces. The software features a comprehensive help function. The various elements of the experiment are clearly laid-out and housed securely in a storage system
