Systematic error

eliminating almost all forms of systematic errors. However, time constraints often determine whether or not this can be achieved, and in this case, there was not enough time to repeat the process with new equipment. Repeating the experiment with the same equipment is also very important. The more results collected, leads to a higher precision and therefore and more statically correct mean. This particular titration displayed the number and extent of random errors as quite significant. This is…

graph also indicated low scatter and high precision between increments as the average points are close to the line of best fit. As shown in the second graph comparing the linen of true value with the average line of best fit there is obvious systematic error in this experiment, the two lines are too far apart to suggest high accuracy in the results although both lines have a very low gradient showing that they share similar characteristics when the relationship between variable is…

scatter, and consisted of an outlier in the sample in which the ratio of NaCl: deionised water was 10:30mL. The outlier and scatter may have been due to random errors, which caused the results to be unreliable. Due to this, the raw data does not support the hypothesis. Thus, a line of best fit was drawn in order to reduce the effect of random errors, and statistically remove the outliers, to give a better representation of what the results should have been. This line of best fit suggests that…

1. Describe your level of awareness of the prevalence of medical errors before this course and reading part 1 Before reading part 1, I was in the delusion that medical mistakes occurs and are extremely rare. After reading the part 1, I realized that medical mistakes are not as rare as I thought it was. According to Institute of Medicine report (IOM) report, nearly 98,000 thousand people die each year from preventable medical error (Gibson, & Singh, 2003). 2. Part 1 of Gibson and Singh details…

one another, thus meaning that the variable of time was strictly not controlled within the experiment. Small test to test discrepancies in pressure gage reading is another area in which random error may have occurred. As the scaling of the bicycle pump increased in values of 2 PSI, the assumed margin for error is 1…

total, 98 errors occurred in this experiment. An error occurred when the line drawn went over a bound of the maze. The first maze without the mirror had 1 error and took 18 seconds to complete. Using the mirror, the second maze had 22 errors and took 75 seconds to complete, the third maze had 22 errors and took 88 seconds to complete, the fourth maze had 18 errors and took 94 seconds to complete, the fifth maze had 6 errors and took 56 seconds to complete, the sixth maze had 11 errors and took…

11a, lab 1: Motion, Measurement and Statistics In the first lab we will investigate the motion of a ball rolling down an inclined plane. We will use this simple system to investigate the concept of systematic and random measurement uncertainties to understand how much we can trust a measurement. We will then compare the experimental outcome with theory. I. Ball on an inclined plane: Measuring motion We want to measure the motion of a ball that rolls down on an inclined plane…

Workflow Design: Clinical Scenario The purpose of this paper is to explore a clinical scenario, answer pertinent questions, and list out the correct steps for administering an oral medication according to the “five rights” of the medication administration process (Edwards & Axe, 2015; Hunter, 2011). In addition, a workflow diagram was created to demonstrate the process from start to end. Scenario Analysis As healthcare providers, nurses are trained to follow the “five rights” of the…

on the x- axis leading to a gradient of 1/√g. Two lines of best-fit are to be found; one using the standard high/low method and secondly one using the unweighted method of least squares. Gradients are found for each of theses lines (along with its error when using the unweighted method of least squares) and these values rearranged to find the value for gravitational…

INTRODUCTION The workplace conditions and safety climate related-programmes, especially in emerging industrial countries, are remained poorly neglected (Bosak, Coetsee, & Cullinane, 2013). For instance, Indonesia as an emerging country has three major issues regarding psychological safety, labour market security and quality of the working environment issues such as poorly paid salary and wages, long working hours, accidents, etc. (OECD, 2014). In fact, Jamsostek (2013) reports that work…
