...Simulation with Arena Assignment G2: a multi-echelon inventory policy Christopoulou Evdoxia Kuodzevicius Bernardas 101283 534893 10/12/2012 Preliminaries The given Arena model is a steady-state model, because there is no clear event that could indicate the end of model run and actually we are interested in the long run behavior of the system represented by the given model. Before we start to do the main parts of the assignment, that is design of experiments and optimization, we conduct some preliminary experiments to check if the model could be modified in order to get better results. First we set the number of replications to 30 and we choose the length of each replication be 730 days (two years), which we think should be enough to reach the steady-state. When we run the model with these settings, we get that the mean of the main response variable - average cost - is 568.4 and the half width is equal to 2.37. Although the confidence interval is not extremely wide taking into account the relatively high value of mean, we still perform a check whether it is possible to get more precise results by using common random numbers. To figure out if the model would benefit from the use of CRN we perform a pilot study. In this study we need to have two different scenarios and then we can decide whether it is useful to use CRN by checking the following inequality: { } { } { } and if this inequality holds, then it is worth using CRN in the model. In our case the scenarios differ in three...

...and statistics are two related but separate academic disciplines. Statistical analysis often uses probability distributions, and the two topics are often studied together. However, probability theory contains much that is of mostly of mathematical interest and not directly relevant to statistics. Moreover, many topics in statistics are independent of probability theory. Probability (or likelihood) is a measure or estimation of how likely it is that something will happen or that a statement is true. Probabilities are given a value between 0 (0% chance or will not happen) and 1 (100% chance or will happen). The higher the degree of probability, the more likely the event is to happen, or, in a longer series of samples, the greater the number of times such event is expected to happen. These concepts have been given an axiomatic mathematical derivation in probability theory (see probability axioms), which is used widely in such areas of study as mathematics, statistics, finance, gambling, science, artificial intelligence/machine learning and philosophy to, for example, draw inferences about the expected frequency of events. Probability theory is also used to describe the underlying mechanics and regularities of complex systems. Statistics is the study of the collection, organization, analysis, interpretation and presentation of data. It deals with all aspects of data, including the planning of data collection in terms of the design of surveys and experiments. The word statistics, when...

...Chapter 3 Methodology Historical Research Design purpose is to collect, verify, synthesize evidence to establish facts that defend or refute your hypothesis. It uses primary sources, secondary sources, and lots of qualitative data sources such as logs, diaries, official records, reports, etc. The limitation is that the sources must be both authentic and valid. When we think of research, we often think of a laboratory or classroom where two or more groups receive different treatments or alternative training methods. We would then determine if the treatment or training had an impact on some outcome measure. This type of research is the best at predicting cause and effect relationships and is often cited as the most rigorous and standardized form. While the experiments described above have a definite place in the research arena, sometimes we gain the best knowledge by looking into the past rather than into the future. Historical research attempts to do just that. Through a detailed analysis of historical data, we can determine, perhaps to a lesser extent, cause and effect relationships. We can also help prevent the present day teachers, managers, and other users of research from making the same mistakes that were made in the past. Historical research can also mean gathering data from situations that have already occurred and performing statistical analysis on this data just as we would in a traditional experiment. The one key difference between this type of research and...

...Goudy RES/351 July 6, 2015 Tracy Sipma Descriptive statistics Descriptive statistics suggests a straightforward quantitative outline of a data-set which has been gathered. It helps us comprehend the experimentation or data-set in-detail and tells people concerning the mandatory details that help show the data perceptively. Descriptive statistics, we just convey exactly what the data reveals and tell us. Most of the statistical averages and numbers we estimate are essentially illustrative averages. For instance the Dow Jones Industrial tells us about the typical performance of select firms. The grade-point avg. tells us about the typical performance of a pupil in school. The GDP growth rate tells us about the typical performance of a state. Therefore illustrative statistics attempts to catch a sizable group of observations and offers us some concept concerning the data-set. Descriptive statistics aims to describe data set information with summary graphs and tables (Linda Hollis, n.d.). Inferential Statistics Inferential statistics includes drawing the correct conclusions from your statistical evaluation that's been performed using descriptive data. Ultimately, it really is the inferences that make studies significant and this element is dealt with-in inferential data. Most forecasts of the potential and generalizations of a population by analyzing a smaller sample come under the scope of inferential statistics. Many social sciences experiments offer with analyzing a little...

...on the credibility of the research. The research process involves ways and strategies that enable researchers to analyze and understand the researched information. The research process involves a dedicated system of scientific methodology that can be used by researchers to arrive at the right conclusions. Some terminology learned in this week’s reading includes statistics, population, census, sample, subjects, variables, margin of error, and bias. Statistics has many uses, but perhaps its most important purpose is to help us make good decisions about issues that involve uncertainty. Speaking of statistics, some may ask what statistics are. The meaning of statistics in singular form is the science that helps bring meaning and understanding to the collection, organization, and interpreting of data. When speaking of statistics in plural form it is the actual data that is used to describe the information. In the language of statistics, population refers to the statistical study of the entirety of the characteristic that the study is focused on. While population is usually seen as a group of people, in statistics population could be a group of animals or things in addition to people. The collection of data from individual members of a population is called a census. Due to populations being so large it becomes troublesome to conduct a census, so the data is typically gathered from a sample. When discussing population, sample is a term that will also stand out. According...

It is designed to help students learn about what is involved in undertaking basic statistical analysis to understand a real-world problem, and communicating the results of this analysis to business stakeholders. Context and Problem You are working as a business analyst for Crunch-IT Consultants, a Sydney-based company that specializes in providing statistical consulting services to small and medium-sized companies. Your company is contacted by AdVantage, a designer of online advertisements whose business model is based on selling their design services to businesses that place ads on social media sites. You attend a breakfast meeting with a senior Crunch-IT consultant and AdVantage’s owner-operator, Arnold Valenzuela, to discuss Arnold’s concerns. At the meeting, Arnold says: “Well, first, I’d like to know whether any of the four designers I’ve hired are underperforming relative to their peers. It’s easy to see that there are big differences across my designers in the styles of their ads, and I can’t help thinking that maybe some styles drive traffic better than others – but maybe that’s not the case. Of course, as with any business, ensuring I am offering a value proposition to clients is key to generating repeat business and word-ofmouth...

...Academic Stress and Emotional Eating among Selected College Students A Thesis Proposal Presented to the Department of Psychology Far Eastern University In Partial Fulfillment Of the Requirements of the Degree Bachelors of Science in Psychology By Alingayao, Liezel O. Esporlas, Mara Alexandria F. Hablero, Maritony E. Pilones, Edrick V. Siano, Silka Andrea M. Torrecampo, Lyana Nicole B. CHAPTER 3 Research Methodology This chapter contains the research design of the study, which is the description of the participants and the techniques for gathering the respondents. Furthermore, this chapter discusses the data gathering procedures and the statistical treatment of the data. Research Design The researchers used descriptive design, which are the comparative and correlational methods. Descriptive method is used to obtain information concerning the current status of the phenomena to describe what exist with respect to variables or the conditions in a situation (Key, 1997). Comparative study identifies the similarities and the difference between the variables across societies. Correlational study determines whether or not two variables are correlated (Kalla, n.d.). Looking for a variable that seems to interact with each other, so that when you see one changing, you have the idea of how others will change (Devin, 2015). These methodologies were applied in order to find the significant differences and similarities of academic stress and emotional...
