False precision

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 distance of the paintball shot from a 40 degree angle. An inference made as to why the results turned out the way they did was because, once the paintballs had been shot from 35 degrees the angle continued to increase, which caused the paintball to be shot from higher angles. This caused the paintballs to travel higher rather than traveling farther away from the paintball gun. One outside factor that could have changed the results was the type of brand of the paintball gun used to fire the paintballs. There were many factors of the experiment that went well. One of these factors was the paintball gun functioned properly. Another factor that went well was the point were the paintball hit the ground was able to be seen, which caused the results to be recorded accurately. One factor that did not go well during the experiment was the distance the paintballs traveled at 85 and 90 degrees was not able to be recorded because the paintballs traveled too high which caused them to go in many…

Editing information, another aspect of totalitarianism, is terrifyingly prevalent in the 2016 election. Donald Trump, the forty-fifth President of the United States, has had one of the most controversial campaigns in history. Many question how he moved from a life of hosting TV shows to the White House so easily. The answer is simple: his use of falsehoods to psychologically manipulate the public. Trump’s presidency has been full of lies. Whether you are a supporter or not, it is clear that he…

20° the reaction sped up four times as much, 30° three times and so on. This conclusion could help evaluate the results as it corresponds to the curve of the graph. As the curve escalates more dramatically as the temperature is increased by 10°C each time it supports this assumption and in turn supports the hypothesis that an rise in temperature means a drop in reaction time. The Rate of Reaction Vs. Time also supports these conclusions. As the temperature increases so does the rate of reaction…

2B.Which Glassware had the smallest precision and the largest precision? You can use the equation for standard deviation to measure the precision then you can compare the precision from each glassware to each other. The graduated cylinder produces results that are the most consistent, therefore the most precise,…

number is considered exact, it does not affect the accuracy of a calculation. When taking significant figures into account for a problem, exact numbers will not affect them either. When performing a measurement on a digital instrument, read and record all of the numbers as displayed, including zeros after the decimal point. But on a scaled instrument, estimate one more figure than you can actually read from the scale. This accounts for the inaccuracies and errors that occur naturally. Accuracy…

In the future, I intend on having career in the medical field, where accuracy and precision is crucial in many aspects of that field, such as calculating the dosage of medicine for a patient. To ensure that the calculation in accurate and precise, I would apply this method of testing various instruments of measurement. The use of density is also important for those who work in fields related to overseas shipping because obviously their goods need to stay afloat in the water, and calculating the…

first part of the experiment consisted of finding the accuracy and precision of three different measuring devices, a 50mL beaker, a 25mL graduated cylinder and a 25mL pipette. The mean volumes and uncertainties were found to be 22.5mL 1.9, 23.72 .25, and 24.89 .43, respectfully. The 25mL pipette was found to be the most accurate out of the three. The density of water was found to be 0.9979 g/cc with a percent error of .08, while the known density of water being 0.997041 g/cc. For the second…

Outgassing of carbon dioxide (CO2) from inland waters has been estimated to offset approximately 20% of net uptake of carbon into the terrestrial biosphere. However, this calculation is based on estimates of source strength at the air-water interface that is highly uncertain [Ciais et al., 2013]. One of the largest unknowns is the accuracy and precision of freshwater partial pressure of CO2 (pCO2) estimates. To better understand observational uncertainty in CO2 flux from inland waters, here we…

According to the article, “McMahon Group distributed mail surveys to 1,650 members and their spouses in January 1999” (Cooper & Schindler, NCRCC: Teeing Up a New Strategic Direction, 2001, p. 2). With the return rate of over half of the surveys, the sampling was very representative of the population it represented. Everyone that took the survey should have been affiliated with the NCRCC or care about the outcome of the data. Cooper and Schindler (2014) also provide that the sample must be…

Summary of: Superman to the rescue: Simulating physical invulnerability attenuates exclusion-related interpersonal biases In the article, Superman to the rescue: Simulating physical invulnerability attenuates exclusion-related interpersonal biases, the authors, Julie Y. Huang, Joshua M. Ackerman, and John A. Bargh (2013) address the theory that simulating physical invulnerability can affect exclusion-related positive and negative feelings toward in and out-groups. The researchers want to test…
