Accuracy and precision

1. What are the potential sources of the problem? One major potential source of the problem that Interwest Healthcare is facing is that management cannot effectively communicate the importance of accurate data entry to the hospital staff. With the management reports compiled from the system, there could be concerns for cost allocation with the different treatments. If any mistakes are made while entering the data, it could lead to miscalculations concerning different treatment cost. While a…

her patients when they first came into the rehab. Courtney also worked with a team of specialist like dietitians, physicians’ assistants, nurses and therapist, and met with those specialists to discuss the patients discharge planning, and progress (). The rotary rehab team did that also. The things that are different in Courtney story from the agency I observed is the death board that Courtney agency used every day to put the names of the patients that has passed away (), and her outpatient…

Accuracy and Precision Lab Report By Connor MacFarland 10.23.2016 IBC 1 Question What is the difference between accuracy and precision and how can we demonstrate the difference? MATERIALS Pencil Notebook Paper 100 mL Graduated Cylinder 1 Gallon of water Ruler Unmarked Plastic Container 3 different kinds of Rocks of different sizes Triple Beam Balance PROCEDURE Estimating Lengths Procedure A piece of notebook paper was torn into 8 rectangles Without a ruler, a line was drawn which…

Conclusion The hypothesis for the best angle to shoot a paintball to achieve the farthest distance possible was rejected.The data from the experiment that supports this conclusion is, the distance of the paintball that was shot from a 35 degree angle traveled, on average, 126.56 meters. This distance is 2.84 meters greater than the average distance of the paintball shot at 30 degrees. The average distance of the paintballs shot at 35 degrees was also, 15.31 meters larger than the average…

outside of our reach. Proxima b’s key features include a mass of about 1.3 Earth masses, 11.2 day period, and an equilibrium temperature that allows water to be liquid on its surface. Data for this study comes from two radial velocity tools, High Accuracy Radial velocity Planet Searcher (HARPS) and Ultraviolet and Visual Echelle Spectrograph (UVES); both instruments come from European Southern Observatory (ESO). According to the article Planet Candidate Orbit[s]…

what a person is asking or consideration of the problem to be. Accuracy: to represent something in accordance to the way it actually is. Accuracy can be evaluated by the element of Information. Accurate data, facts, observations, and experiences are needed components in reasoning in utilizing evidence to arrive at a sound conclusion. Precision: given details that necessary for someone to comprehend exactly what is meant. Precision can be evaluated by the elements of reasonings Implications and…

targets and two other groups received static target. Result shown that the accuracy for overall performance was around 65-70%, not significantly differed from experiment 1. Also, there were no significant difference between static and live group. From experiment 1 and 2, we can conclude that there is no significant difference between using live target or static target in the identification process. Further, the rate of accuracy on both methods were concerning, since there is 1 out of 4 chance…

validation was performed for fallowing method for these analytical parameters System suitability, Accuracy, Precision, Linearity, LOQ, LOD, Robustness. a) Accuracy The closeness of agreement between the value, which are accepted either as a conventional true value or an accepted reference value and the value found. Accuracy is represented and determined by recovery studies. b) Precision The precision of an analytical procedure expresses the closeness of agreement between a series of…

In the lab, precision, proximity to other experimental values, and accuracy, and proximity to the scientific value were illustrated through the line graph and the Percent Error calculations, the line graph depicting precision and the Percent Error calculations for accuracy. The line graph indicates the lack of precision in this lab, as the class data points were sporadic and distant from each other. The Percent Error calculations portrayed lack of accuracy, as Mineral A and B were the…

Table 4.2 System suitability results for Lamivudine, Zidovudine and Nevirapine Parameters Lamivudine Zidovudine Nevirapine Retention time 2.327 2.864 5.608 Area 212473 338930 228426 USP Plate count 2715.09 3350.07 4979.51 USP Tailing 1.38 1.32 1.18 4.3.1.2 Linearity A linear correlation coefficient factor was obtained between the concentrations of Lamivudine, Zidovudine and Nevirapine versus the peak area. The calibration curves were linear for concentrations between 15-150 µg/mL. The linearity…
