...Statistics is the study of the collection, organization, analysis, interpretation and presentation of data.[1][2] It deals with all aspects of data, including the planning of data collection in terms of the design of surveys and experiments.[1] The word statistics, when referring to the scientific discipline, is singular, as in "Statistics is an art."[3] This should not be confused with the word statistic, referring to a quantity (such as mean or median) calculated from a set of data,[4] whose plural is statistics ("this statistic seems wrong" or "these statistics are misleading"). Some consider statistics a mathematical body of science that pertains to the collection, analysis, interpretation or explanation, and presentation of data,[5] while others consider it a branch of mathematics[6] concerned with collecting and interpreting data. Because of its empirical roots and its focus on applications, statistics is usually considered a distinct mathematical science rather than a branch of mathematics.[7][8] Much of statistics is non-mathematical: ensuring that data collection is undertaken in a way that produces valid conclusions; coding and archiving data so that information is retained and made useful for international comparisons of official statistics; reporting of results and summarised data (tables and graphs) in ways comprehensible to those who must use them; implementing procedures that ensure the privacy of census information. Statisticians improve data quality by developing...

...The accomplishment that I have achieved during this course is the understanding of Compounded Interest. Once I understood the concept of compounded interest, I had to figure out what Compounded Interest meant. I needed to figure out the formula which was complicated, because the interest is compounded repeatedly, meaning the interest is paid on the total being borrowed and then the new amount is charged interest again. It is repeated for each increment of time, such as annually, monthly, weekly, or daily. In order for me to calculate any type of interest I need to know the principal, interest rate, time duration and whether it is a simple or compound interest rates loan. I realized that the principal is the amount of money that is borrowed and needs to be repaid plus interest. The interest rate is the percentage of the principal. The time duration is the length of time, usually in years or months, until loans needs to be repaid. I finally figured out the formula, which is I=prt, where I= interest, P= principal, r=rate of interest, and t= the time duration of the loan. After my husband and I purchase a car with a down payment of $11,000, at a 5.75% interest for 60 months, the compounded interest really began to kick in somewhat. At the end 5 years, we would have paid a total of $17,235.20, with a car note of $103.92 The concepts that I am still struggling with are negative and positive integers, especially simplifying, and algebraic expressions, I had to first understand...

...emphasis particularly on statistics as a core measureable expertise for students in this specific program. The Mathematical Association of America stresses that students in social science majors require a strong foundation in mathematical literacy. The degree I am studying for at Westwood College is an associate’s degree in applied science. So, by me taking mathematics serious and working hard it would benefit me in the long run. Programs predominantly want people studying Criminal Justice to be competent in statistics in order to succeed in a data compelled career field. The specific career I want to perform when I receive my degree is becoming a police officer. Police officers use mathematics in the field everyday. Police are usually the first to the scene when an accident transpires. Police measure impact angles after car accidents, measure skid marks, build statistical models of crime patterns to put patrol officers where thy need to be and a whole lot more. Math is generally used to prevent crime because without mathematics crime would not be as detectable. All police officers use mathematics while patrolling the field. For instance, say someone is pulled over for a DUI, the police use Breathalyzer’s to measure the blood alcohol content of the person they suspect of drinking and driving. This may do most of the math for the officers, but they still need to know how the machine itself calculates the blood alcohol content. Police officers use math while handing out traffic...

...Statistics in Business Kathleen S. Power-Davenport QNT/351 May 25, 2015 Lance Milner Statistics in Business Introduction Statistics is "the science of collecting, organizing presenting, analyzing, and interpreting data to assist in making more efficient decisions" (Lind, Marchal & Wathen, 2011). This paper will summarize the types, levels, and the role of statistics in business decision making, followed by examples of statistics in action. Types, Levels, and the Role in Business Decision Making The two categories of statistics are descriptive and inferential. Descriptive statistics is the analysis of data that describes, or summarizes the data in a meaningful way (Laerd Statistics, 2013). Business leaders can organize large amounts of data into a comprehensive format utilizing descriptive statistics. But descriptive statistics do not make conclusions about the data. An inferential statistic is calculated by taking a sample of the data from the population, and drawing a conclusion about the whole based on the small amount (Lind, Marchal & Wathen). Decision makers move forward based on a conclusion drawn from statistical inference. The data gathered for statistics is classified into four levels of measurement: nominal, ordinal, interval and ratio (Lind, Marchal & Wathen). Data at the lowest level is nominal and has a qualitative variable divided into categories or outcomes. Ordinal data is qualitative and represented by sets of labels or names...

...Descriptive and Inferential Statistics PSY/315 Statistical Reasoning in Psychology September 21, 2013 Dr. Nancy Walker Descriptive and Inferential Statistics Statistics is “a branch of mathematics that focuses on the organization, analysis, and interpretation of a group of numbers” (Aron, Aron, & Coups, 2009, p. 2). However, just the mention of statistics makes people nervous, although when properly understood, many of the questions statistics tries to answer are very provocative and challenging. Statistics are a collection of information and, data that helps test the theory something is happening or will happen again. The functions of statistics are there to help researchers have a better understanding of a phenomenon. Statistics can be used when looking for the truth, if you have ever had a hunch about something, was it confirmed? Yes the hunch was confirmed. Statistics help researchers with data by using math and working with a group of numbers. Statistics studies variables, characteristics that have different values, values, possible number that a score can have, and score one person value of a variable (Aron, Aron, & Coups, 2009). Descriptive and inferential statistics are to evaluate results and enable one to make a conclusion. Descriptive statistics are a way to describe data (Laird Statistics, 2013), as well as to “summarize and describe a group of numbers from a research study,” whereas, inferential statistics are used to “draw conclusions and...

...Final Project: Math Used in the Paralegal Profession Misty Kenter Kaplan University MM150 Prof. Mowen May 21, 2011 INTRODUCTION This paper is on what kind of math I will be using in my chosen profession. My chosen profession is the paralegal profession. I know that I will not need to know a lot of math for this profession. As a paralegal professional I will be using math every day. I will be using math for everything from keeping track of billable hours to estimating damages in a lawsuit. I will need to know basic math, basic algebra, and first year algebra. Basic math and basic algebra consists of addition, subtraction, multiplication, fractions, decimals, percentages, and negative numbers (www.xpmath.com). First year algebra consists of using formulas (www.xpmath.com). In this paper I will explain in detail the math that I would use in the four different types of law offices for a paralegal professional that I am interested in. These types of law offices are family law, civil litigation, probate and estate law, and criminal law. Family Law In a family law office I would use basic math and first year algebra. I would be using addition, subtraction, multiplication, division, and a formula set by the courts to calculate child support and spousal support payments. I also would be using addition, subtraction, multiplication, and division to figure out how much the marital property is worth and how much each party would get if the clients decide to sell the property...

...Question 1: Conceptual Question (a) Model I: The major econometric issue is on the error term ui. The equation ui2=γ1+γ2x1,j indicates that the error term ui is related with the independent variable x1. Under the general assumptions, the error term us designed to capture ‘unexpected’ events, as such the error term should be random and the independent variable x1 is not random which means that its value if known. Therefore, model I breaks out this assumption, the error term ui is related with the independent variable x1 (not random), error term uiwill hence be not random as well. As a result, the dependent variable y will be not random which is wrong in econometrics. (b) Model II: The major econometric issue is on the error term vt. The equation vt=ρvt-1 indicates that for the pair of random error term vt and vt-1, there is linear association among them. Under the fourth assumption of the simple linear regression model, the covariance between any pair of random errors is zero, implying that there is no linear association among them. Therefore, model II breaks out this assumption, one random error term vt has a linear relationship with another random error term vt-1. (c) Model III: The major econometric issue is on the independent variable x1,i. x1,i~i.i.d(ux, σx2) indicates that x1,i is independent and identically distributed random variables. Under the fifth assumption of the simple linear regression model, it requires the regressors x1,i to...

...who try to make differences in our schools that can help and benefit high school educations that will help the students when it is time to leave into the real world. In opinion many schools tend to make the classes mandatory in hopes that it will help students even if they do not choose to, but that is not the case all the time. Many students might fail more if you make them take it mandatoryly rather than letting the students have a choice. In the New York Times October 6th, 2013 article “Financial literacy, beyond the classroom” by Richard H. Thaler, Shawn Cole states that “We find no effect,”he said. “My gut feeling is that teaching math and statistics would be more useful.” This statement in opinion is false because financial literacy classes are equally if not more important than math and statistics and will as well as math and statistics help students in their life after high...

From the results of analysis from the sample data, we can predict the results from the population. Some questions that one may want to answer are 1. Are unmarried workers more likely to be absent from work than married workers? 2. Are the sixth graders in a certain school significantly less skilled in their mathematical abilities than the average student in the district? 3. In Fall 1996, did students in Math 163-01 score the same on the exam as students in Math 163-02? 4. Is there any difference between the strengths of steel wire produced by the XY Company and Bob’s Wire Company? 5.
