in a review of experimental evaluations of PD programs in developed countries, Yoon et al. (2007) found that the academic achievement of students whose teachers participated in PD programs (about 49 hours of training on average) increased by 0.54 standard deviations compared to students whose teachers did not participate in PD. These positive findings lend credence to the efforts of policymakers from developing countries who are in favor of using PD to improve the quality of teaching in their…
exists in America. Phillips and Lowery (2015) identify Caucasians as the most privileged of all races. They claimed that whites had better earnings (Hao, 2011) greater life expectancy (Bleich, Jarlenski, Bell, & LaVeist, 2012) better access to health care (Smedley, Stith, & Nelson, 2003) and high-quality education (Rumberger, 2010) than other races, specifically African-Americans. As a result of their view of life in a meritocratic way, they are unable to acknowledge their own racial privilege…
lifestyle factors and willingness to engage in self-care scores there are a total of 14 participants. The levels of central tendency consist of the mean of 5.5 which is the average score, the median of 5.5 which is the exact middle number and the mode of 7 which is the most frequent occurring score (Salkind, 2013). There was an average deviation from the sample mean of 2.35, therefore it can be said that 95% of cases would fall between -2 standard deviation (SD) and +2SD (Loiselle et al., 2011).…
of his competition and expanded into new and profitable markets. By this time, in 1882, Rockefeller established what was known as the Standard Oil Trust which established itself to coordinate all oil exploration, production, and distribution activities throughout the nation. In reality the trust was a giant conglomerate of many small corporations. Having Standard Oil well established, by the 1890s, Rockefeller’s empire controlled almost 90% of all oil that was produced in America. His ventures…

In this project, I will analyze the problem of gender inequality in terms of labor income. This problem is important in our society because people with same background and same experience should be treated the same in the same working environment. Women should not be judged based on their biological gender. The data sample used in this project is working individuals between ages 25 and 54 from Current Population Survey, 2012. Sample size contains 999 observations. I will first discuss the…
making. Today, I write to you to express my concern about one specific issue, ocean acidification. Ocean acidification is often swept under the rug when it comes to talking about pollution and climate issues. It is a difficult concept to grasp and care about as we do not see it every day, however, it is a danger to not only our way of life but human life in general. Ocean acidification refers to a reduction in the pH of the ocean over an extended period of time, caused primarily by uptake of…
should be at close to $25.00 per hour (Dalton, week 6). The interquartile range pros are that it more accurately represents the majority of data. Its cons are it ignores the most extreme data points. The variance is mainly used in calculating the standard deviation. The pros are that it helps us get an idea of…
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…
This federal law aims at regulating air emissions from stationary sources such as industries and mobile sources such as vehicles. It was established to authorize the Environmental Protection Agency (EPA) to establish National Ambient Air Quality Standards (NAAQS) that protects the public health through regulation of emissions that have a hazardous effect on air (Sueyoshi & Goto, 2010). The CAA was established in 1963 after several deaths were experienced in 1948 and 1952 due to air pollution. It…
