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…

This assignment will address a one way ANOVA between the variables of section and guiz 3 from the grades.sav data sample Data File Description 1. The context of the data set is based on a sample size of 105 students that states their first and last names and are assigned separate id numbers. The sample contains variables that include the variables to be addressed in this assignment. 2. The variables used in this are section and quiz 3. The section variable, or the predictor variable has a…

The two-sample t procedure is appropriate to use in this experiment in order to see if there is a difference in the two population means of stride length in the two different species, N. rattus and N. squamipes. This is because the boxplots appear to be roughly symmetrical, as well as, both normal quantile-quantile plots look roughly linear. Considering two-sample t-procedures are quite robust to violations of the normality assumption, the t-procedure will likely perform well in this…

The experiment was done to reveal how workouts supplements like C4 can affect the development of humans. Other experiments like this one can also be used to show how some substances may affect the development of humans. In the experiment the independent variable was the amount of the C4 that was placed into each well in the experiment, and the dependent variable was the zebrafish embryos after they were exposed to the C4. In addition, 2 controls were set up, containing a ocean/embryo solution…

employee in the sample took a statistics course or not. Ace would like to examine this data in order to prepare analysis report to the management team. Statistical Results 1. In this study of test scores and took statistics course, each variable in the sample data is characterized by creating a histogram and pie chart, respectively. According to the “Histogram of Test Scores”, Appendix A(2), the data can be described as normally distributed. The descriptive statistics result for the variable…

On April 15th in 1912, one of the most tragic shipwreck happened. The Titanic ship sunk under the Atlantic Ocean after colliding with an iceberg. A lot of people died during the accident. Small number of available lifeboats was one of the main reasons that led to such a high number of deaths. Such factors as sex, class, age, and others also significantly contributed to the likelihood of survival. Introducing different statistical methods, I will classify what sorts of people had a better chance…

In the Chi-Square test table below, the “Asymp. Sig. (2-tailed)” determines the level of confidence. This particular level of confidence is less than 0.5, which means the difference is statistically significant. The null hypothesis is thus rejected. Chi-Square Tests Value df Asymp. Sig.
