Become familiar with significant figures and its relationship to measurements and data recording (significant figures). 4. Become familiar with the errors‚ precision and accuracy associated the various measurement tools and techniques. 5. Determine the density of liquids and solids. 6. Determine the best-fit straight line as a method to examine linear relationships and to use this relationship as a predicative model

’Stock Records Accuracy’ means: (1) a correspondence between what is present on the computer file and what physically exists‚ in reality‚ (2) that activities which have been recorded as taking place against stock are truly what in fact occurred‚ and (3) that no activity which took place is unrecorded in the system. As we shall see‚ the central stock file is a most important element of any system within the company. The records within the file are ’keyed’ on each product’s unique item code**. That

Pipetting‚ weighing‚ accuracy and plotting Introduction In this practical‚ there were three parts in which basic skills and key ideas were put into practice as they are essential to working in the laboratory in order to get reliable and valid results; one of the basic skills put into practice was pipetting. This was the main objective for the whole practical‚ as pipettors are the fundamental tools used to measure liquids in laboratories. Not only did this develop the skills and confidence acquired

Experiment 1 (week 2) The purpose of this experiment is to become familiar with the precision and accuracy of scientific glassware. I figured the smaller the glassware the more accurate the measurements would be. Which when we were preforming the experiment proved my theory. As the glassware got smaller the easier it was to get the accurate amount of water into the glassware. We went from a big flask to a small beaker to an even smaller pipette. We used a scale to get the appropriate weight

lives even though we may not realize that chemistry is everywhere. This paper serves to examine the ways in which chemistry is relevant in everyday life and in society. It will also examine the difference between accuracy and precision and provide examples of when accuracy and precision are crucial in measurements and why society depends on these measurements to be accurate and precise ( Tam 2012).

Different techniques will be used to determine these densities and one in particular is mixing the liquids in different proportions to compare the accuracy and precision of your calculated densities to the initial in text values. The reactions being used in this experiment are the liquids and solids. The following is a brief chronological listing of the procedures to follow while conducting the experiment

survive. Accuracy and Precision relate to quality of measurement. Accuracy refers to how close the measurements are to the “true” value or accepted standard value or known value. Precision is how close measurements are to each other. Precision is a unit of measurement that is also referred to as the ability to reproduce the same results multiple times. Society is reliant on standard measurements when they buy goods and services. Society depends upon the accuracy and precision of measurements
