presented both downward and upward trend pattern of nail cuticle-biting behaviors. The mean value of the baseline is 6 and the standard deviation is 1.26. The first intervention phase data a downward trend pattern can be observed, which signifies a decrease in the amount of nail cuticle biting behaviors performed. The mean value of the first intervention data is 2.16, with a standard deviation of 1.47. Once the HRT intervention was applied, the targeted nail cuticle -biting…
effective in analyzing the performance of students. In the case of my quiz, I believe that obtaining a .59 is reasonable. Nevertheless, I plan to review the quizzes I administer and strive to minimize the level of scores that might be in error. Standard error of measurement (SEM) = 1.307. If the deviation of errors of measurement associated with the test scores are high, the accuracy of the scores will be low due to measurement errors. Given a mean score of 7.02, I believe with a 68%…
project, limits of acceptable process variation can be analyzed. Because the quality control process that existed before was to approximately 1% defect rate, new defect rate will be calculated against this value. Polaroid set control limit at 3 standard…
stick where we took the readings in centimeters. We wrote down all our readings in Excel and found the confidence intervals. From the observations, we find that the data is more accurate for normal vision than impaired vision because for the standard deviation for normal vision is far lesser than impaired vision. This means that the value for impaired vision are more dispersed and has more errors. There are certain errors on this experiment too. This is because, both the normal and…
making this sport a profound heritage among different kinds of car enthusiasts. However, this deep embodiment of racing can possibly shatter with the Environmental Protection Agency (EPA) introducing the, Greenhouse Gas Emissions and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles – Phase 2 that resides under the Clean Air Act. This regulation, is a vague proposal that can potentially hurt the vibrant industry of performance parts from automakers, thus hinder car…
globalization (the elephant) as a whole, since each aspect is important, and looking at just one can cause confuse the true nature of globalization. Globalization is a controversial term; for example, some experts believe everyone benefits and the standard of living is rising, whereas other critics point out the growing disparity between the rich and the poor, and point out that everyone is affected differently by globalization. As Steger argues, globalization is a process, not a condition,…
In mid-September 2015, the Volkswagen (VW) scandal erupted in the United States, creating a shockwave in the diesel automobile sector both domestic and international. US authorities accused VW of installing “defeat devices” in nearly half a million cars between 2009 and 2015 to make them appear less polluting than they actually are. Independent tests done by the International Council on Clean Transportation (ICCT) confirmed that a selection of VW vehicles were emitting up to 40 times more…
Smaller sample sizes result in larger standard deviations with a flatter and more spread out distribution. This results in greater estimates of standard error. This is a problem. Slide 7: Let’s talk about beer. Yes, beer. W.S. Gossett, a scientist for Guiness brewery, pondered how each bale of barley affected the quality of the beer produced…

The Discovery and Motion of Particulate Matter Introduction During the 1930s and 50s many scientist studied cosmic rays which were understood to originate from outer space. Many were able to observe that when the cosmic rays collided with atoms in our atmosphere, the nucleus of the atom was prised open by the energy created. This then revealed many short-lived particles within the nucleus. However, these could only be seen in tracks left behind in sensitive detectors. There were many particles…
