Linear mixed models for repeated measurements were conducted with the variable of occupation after injury as a covariate. The results of the linear mixed models showed statistically significant differences between the experimental and the control groups in terms of changes in self-care knowledge (β = 1.696, P = 0.004), selfefficacy (β = 5.547, P < 0.001), and self-care behaviors (β = 11.694, P < 0.001) after the 8 week program. Selfcare knowledge, self-efficacy, and self-care behaviors…

The percent error of the calculated percent water and accepted value is 3.36%. The mean of the class data for percent water was 50.8% and the standard deviation was 0.0300. Compared to the class results, my percent water was lower, but very close to the mean. The standard deviation has a low number; hence the data are not as spread out from the mean. One source of error that contributed to this percent error was that the hydrate, MgSO_4, may have been heated too long. This is a random error…

Numerical Memory Study Consent Form You are being asked to take part in a research study of how much numerical information you can retain. What the study is about: The purpose of this study is to learn how well you can remember a sequence of numbers using the Auditory and Visual tests. What we will ask you to do: If you agree to be in this study, we will provide you with a link to the test via the internet using a classroom number. You will click on the link and begin the test will take…

The question investigated in this experiment was how does the sow bug’s preference of habitat affect the concentration and distribution of the organisms. The purpose of this investigation was to decipher what habitats these organisms prefer to live in and how it would affect their population density. This was tested by a simple experimental design with four petri dishes that each represented a different environment. The control treatment was the dish with just dirt while the other habitats…

The Benefits and Drawbacks to an Interactive Learning Environment One of the greatest challenges in the pursuit of teaching is providing an engaging environment in which students can learn and retain the knowledge gained. In the Stansbury and Munro (2013) experiment, as well as the research conducted by Ciarocco, Lewandowski, and Van Volkom (2013), the goal of each study was to identify the most beneficial of interactive instruction. However, as there is the possibility for improvement in any…

Is America’s academic “boat” being taken over by the Chinese? In the New York Times article, “Amy Chua is a Wimp”, by David Brooks, touches on whether Chinese parenting is better than American parenting, and criticizes one parent’s, Amy Chua, method of raising her own kids. In this piece, Brook uses effective literary strategies in order to turn us against Chua, but at the same time opens our eyes to the idea that she is no better than us Americans. He exploits Chua’s parenting flaws right from…

The area sampled in squared centimeters goes on the x-axis because it is the independent variable. Whereas species richness goes on the y-axis because it is the dependent variable. Based on this sample the prairie habitat seems to be more species rich. This approach does not provide a definitive answer to the question because this is a single sample. In order to provide a more accurate answer to the question of which habitat is richer, more samples must be included and analyzed in order to…

This paper will study the relationship between a country’s perceived amount of corruption, and how that affects the wages of its domestic workers. The premise behind this paper is that a country that is perceived as being dishonest and corrupt would have lower wages. Corruption in government is seemingly always present in our world. This paper will try to determine if there is a correlation between a country’s perceived corruption and the monthly disposable income its workers earn with…

Purpose To investigate the effect of temperature on the rate of the thiosulphate reaction. Hypothesis If the temperature increases, then the rate of the thiosulphate reaction will also increase. Variables Independent variable: Temperature change in each experiment, which will be varied by increasing the temperature by 10°C each time. Dependent Variable: Rate of reaction, which will be measured by measuring the time taken for the cross to not be visible. Constants: Concentration of HCl and…
