...Variables1, in statistics, are any characteristic that varies with the members of the population. For example, Dr. Blackbeard’s Stat 101 class had a test and the results are in and not all had an equal score. Some score higher than others, and some scored lower. Thus, the test scores are considered a variable which in this case is a whole number between 0-25. Another variable is the amount of time the students took to study for the test. In this case, the variable varies between a second, minute, hour, or maybe even a tenth of a second. So, variables can differ depending on the situation or the information which is given. Now two types of numerical variables2 are discrete and continuous. Discrete3 is like IQ scores, SAT scores, a person’s shoes size, and so on. Continuous4 is more along the lines of height, weight, and age. Sometimes in the real world the distinction between continuous and discrete variables can be a blur. Height, weight, and age are considered continuous in theory, but they always seem to be rounded off to the nearest inch, ounce, or year, at which point they become discrete. On the other hand, money, which in theory is a discrete variable (because the difference between two values can’t be less than a penny), is mostly thought as a continuous variable because in most real life situation a penny can be thought of as an insignificantly small amount of money. Variables can also be used to describe gender, hair color, nationality, and so on. These variables are...

...Name Date: Math 7a Worksheet #7 Lesson 7: Unit Rate as the Constant of Proportionality DO NOW: Example 1: National Forest Deer Population in Danger? Wildlife conservationists are concerned that the deer population might not be constant across the National Forest. The scientists found that there were 144 deer in a 16 square mile area of the forest. In another part of the forest, conservationists counted 117 deer in a 13 square mile area. Yet a third conservationist counted 216 deer in a 24 square mile plot of the forest. Do conservationists need to be worried? a. Why does it matter if the deer population is not constant in a certain area of the national forest? b. What is the population density of deer per square mile? Table: | | | | | | | | | | | | | | | | The Unit Rate of deer per 1 square mile is _______. The Constant of Proportionality: Meaning of Constant of Proportionality in this problem: c.

...Do Peers Affect Student Achievement? by Eric A. Hanushek, John F. Kain, Jacob M. Markman, and Steven G. Rivkin* December 1999 Abstract Empirical analysis of peer effects on student achievement has been limited, and what exists has been open to question because of the difficulties of identifying peer effects per se. Our strategy to identify peer group effects involves the elimination of problems introduced by unmeasured or mismeasured influences on achievement through the estimation of achievement growth models with fixed individual and school-by-grade effects. Our basic estimation of elementary school achievement growth indicates that the achievement level and racial composition of peers has a direct influence on achievement. All students appear to benefit from having higher achieving schoolmates, although the effect is quite small. The variance in achievement appears to have no systematic influence, and the effects of mean differences in peer achievement levels are roughly constant across quartiles of the achievement distribution – suggesting that ability grouping policies have primary influence on the distribution of performance and not the level. Moreover, ceteris paribus schools with higher concentrations of minority students lead to lower achievement for Black students but minimal effects on whites or Hispanics.

...A Statistical Perspective on Data Mining Ranjan Maitra∗ Abstract Technological advances have led to new and automated data collection methods. Datasets once at a premium are often plentiful nowadays and sometimes indeed massive. A new breed of challenges are thus presented – primary among them is the need for methodology to analyze such masses of data with a view to understanding complex phenomena and relationships. Such capability is provided by data mining which combines core statistical techniques with those from machine intelligence. This article reviews the current state of the discipline from a statistician’s perspective, illustrates issues with real-life examples, discusses the connections with statistics, the differences, the failings and the challenges ahead. 1 Introduction The information age has been matched by an explosion of data. This surfeit has been a result of modern, improved and, in many cases, automated methods for both data collection and storage. For instance, many stores tag their items with a product-specific bar code, which is scanned in when the corresponding item is bought. This automatically creates a gigantic repository of information on products and product combinations sold. Similar databases are also created by automated book-keeping, digital communication tools or by remote sensing satellites, and aided by the availability of affordable and effective storage mechanisms – magnetic tapes, data warehouses and so on. This has created a situation...

...Preface During the past century, the impact of mathematics on humanity has been more tremendous than ever since Galileo's agonizing fight against the old establishment and the revolution which physics experienced after Newton's subsequent synthesis. At the beginning of the last century, mathematical ideas and techniques were spread to theoretical and applied physics by the influence of two of the greatest mathematicians of all times, D. Hilbert and H. Poincar6, being then at the zenith of their careers. Their ability to establish very deep at first glance often hidden connections between a priori separated branches of science convinced physicists to adopt and work with the most powerful existing mathematical tools. Whereas the 20th century really was the century of physics, mathematics enjoyed a well deserved reputation from its very beginning, so facilitating the huge impact it had subsequently on humanity. This reputation has been crucial for the tremendous development of science and technology. Although mathematics supported the development of weapons of mass destruction, it simultaneously promoted the advancement of computers and high technology, without which the substantial improvement of the living conditions humanity as a whole has experienced, could not have been realized. In no previous time the world has seen such a spectacular growth of scientific knowledge as during the last century, with mathematics playing a central role in most scientific and...

Article Evidence for the Latent Factor Structure of the MSLQ: A New Conceptualization of an Established Questionnaire SAGE Open – October-December 2013: 1 10 © The Author(s) 2013 DOI: 10.1177/2158244013510305 sgo.sagepub.com Jonathan C. Hilpert1, Jennifer Stempien2, Katrien J. van der Hoeven Kraft3, and Jenefer Husman4 Abstract The Motivated Strategies for Learning Questionnaire (MSLQ) has a long history of use in educational psychology, yet few studies have examined the latent factor structure of the entire scale using data from a single administration of the instrument. Although using the subscales individually was encouraged by the creators of the instrument, the practice has produced piecemeal evidence for the latent factor structure. In the current study, we administered all 15 subscales of the MSLQ to a large population of postsecondary students enrolled in introductory geoscience courses and used confirmatory factor analysis to examine the latent factor structures described in previous MSLQ literature. Faced with unsatisfactory evidence for the hypothesized structures, we describe our respecification process and provide some commentary on a more parsimonious latent factor structure that may be of use in similar research projects.

...v _ __________________________________________________________________________ Preface No programming technique solves all problems. No programming language produces only correct results. No programmer should start each project from scratch. Object-oriented programming is the current cure-all — although it has been around for much more then ten years. At the core, there is little more to it then finally applying the good programming principles which we have been taught for more then twenty years. C++ (Eiffel, Oberon-2, Smalltalk ... take your pick) is the New Language because it is object-oriented — although you need not use it that way if you do not want to (or know how to), and it turns out that you can do just as well with plain ANSI-C. Only object-orientation permits code reuse between projects — although the idea of subroutines is as old as computers and good programmers always carried their toolkits and libraries with them. This book is not going to praise object-oriented programming or condemn the Old Way. We are simply going to use ANSI-C to discover how object-oriented programming is done, what its techniques are, why they help us solve bigger problems, and how we harness generality and program to catch mistakes earlier. Along the way we encounter all the jargon — classes, inheritance, instances, linkage, methods, objects, polymorphisms, and more — but we take it out of the realm of magic and see how it translates into the things we have known and...

...Affirmative Action a Balancing Act ENG. 215 February 5, 2013 Affirmative Action a Balancing Act Many people believe that affirmative action laws are reverse discrimination and that these laws should be changed. Unfortunately in this country race is a determining factor in many aspects of daily living. Affirmative action laws simply balance the scales when it comes to determining whether race works for or against minorities. Affirmative action laws should not be changed, because it is an excellent program as demonstrated by the fact that two Supreme Court justices are products of affirmative action. Originally designed to overcome the disparities created by slavery and past discrimination affirmative action is still relevant in today’s society Affirmative action laws have been the subject of legal actions and disputes. In 2003 Michigan law school had to defend its affirmative action practices before the Supreme Court in the case of Grutter versus Bollinger (Garces, 2012). The court decided that colleges and universities have an obligation to consider race in a society where race matters. Another case is currently before the Supreme Court titled Fisher versus the University of Texas (Garces, 2012). A decision in this case is imminent and can have sweeping effects on the future of affirmative action laws. Many Americans do not understand affirmative action laws. Most people see it as a personal injury of giving priority to someone that...
