In Figure 1 we can see a snapshot as of June 29th 2016 of the top major league starting pitchers by ERA. While this only shows basic statistics and is sort-able via any method listed in the columns, you can easily see how these numbers could be gathered, analyzed, and tabulated in a way that could quantify that the performance based on any number of different algorithms depending on what values you were looking for. For example, if someone were interested in who the most durable pitcher is…

William Ward Assignment (no more than 2 pages single-spaced): 1. What does Abelson mean by “Statistics as a principled argument” in your own words? By a principled argument, I believe that Abelson means that there should be a method to statistics. Not necessarily that it should be overly formalized or technical, but one with sound judgement. Abelson argues that good judgement with statistics in social science has been lost because there is considerable focus on null hypothesis testing (Abelson…

In this essay, we present a discussion about Bayesian methods in Spatial Statistics. Bayesian methods are approaches to statistical inferences which have been around for several decades and are also used in Geographic Information Systems. The application of these methods in practical problems has increased significantly within the last few years due to recent advances in tools for computation and simulation [1]. At the heart of any Bayesian data analysis method are the likelihood function, which…

This article used the appropriate statistical procedures for the study. Using descriptive statistics and Pearson’s correlation allows the researcher to reveal if any correlation coefficients among variables are found. Also, using the path analysis to find the relationships among the variables was a key factor. The sample was significant for the study and the path analysis model because it required a large number of cases and this study had 2,565 participants. The responses from the survey…

NYPD currently uses Computer Statistics also known as CompStat as a management tool to maintain data on crime statistics. Through the use of CompStat the department keeps records on crime reduction, personnel and resource management, and improvement in quality of life. It can be considered both a proactive and reactive approach to police management. According to Police Executive Research Forum (2013): For the first time in its history, the NYPD is using crime statistics and regular meetings of…

First, I can't believe we are in week 7!!!!! Back to the topic at hand, statistics. I decided to look up statistics I could find at .org site, just so I could trust the information. I looked up depression statistics. One of the statistics I found was "Major depressive disorder occurs in 6.7% of Americans over the age of 18" (www.dbsalliance.org). I chose this topic specifically because I've seen a lot of antidepressants flying off the shelves. Also for some other personal reasons. How many…

Statistics play a major role in the decisions that businesses make in the companies. This information is used in planning budgets, deciding how many employees to hire etc. This is also used as a factor in the future growth of a business. My employer uses statistics to decide where to put a new plasma center. These could be information on the demographics of the people etc. This paper is about some articles chosen by myself, which relate to the topic. At the end, a summery will conclude the main…

and statistics are provided on products or in the news on just about every aspect, you can imagine. It is as if statistics can be written in a way to draw the audience in. One area that blows my mind is diet products. According to ABC News (2012), the statistics on the diet industry are rather large with upwards of an annual twenty billion dollars in the U.S. spent in the industry to include diet books, drugs and surgeries. We are on the look for weight loss products and when the statistics…
