Define Statistics

More than 100 years ago H.G. Wells, an English author and historian, suggested that one day quantitive reasoning will be as necessary for effective citizenship as the ability to read”. This author was ahead of his times because it affected all the aspects of life, business and personal. Statistics is the science of collecting, organizing, presenting, analyzing, and interpreting data to assist in making a more effective decision. We use statistics everyday of our lives from the moment we wake up and start making decisions to the moment we put our heads back in the pillow at night to go to sleep. Almost every type of major requires us take a course of statistics. There are three major reasons; the first one is because there is numerical information everywhere, second one is that statistical techniques are used to make decisions that affect our daily lives. The third reason is that having the knowledge of statistical methods will help us have a better understanding of how decisions are made and how they affect us.
Types and Levels of Statistics
The types of statistics are, Descriptive Statistics and Inferential Statistics. Descriptive statistics is the method of organizing, summarizing and presenting the data in an informative way. The text use an example of a presentation of the population of the United States from the 1960’s till the present showing the increase on the population throughout the years.
Inferential statistics is the method used to estimate a property of a population on the basis of a sample. What this means they refer to population as a group of people, example “the Cuban population in Miami Florida” that will be consider a specific population. A sample will be utilizing a group of people from this population to conduct a particular study like the average annual income, level of education or any other study you want to...

According to Portney and Watkins (2009), all studies require a description of subjects and responses that are obtained through measuring central tendency, so all studies use descriptive statistics to present an appropriate use of statistical tests and the validity of data interpretation. Although descriptive statistics do not allow general conclusions and allow only limited interpretations, they are useful for understanding the study sample and establishing an appropriate framework for the further analysis in the study. Further analysis using appropriate statistical methods allows the researchers to establish correlations between independent and dependent variables, define possible outcomes, and identify areas of potential study in the future accurately. Statistics is important for researchers because it allows them to investigate and interpret the data more accurately, and researchers will notice patterns in the data that would be overlooked otherwise and result in inaccurate and possibly subjective conclusions (Portney &ump; Watkins, 2009). Frequency distribution is a method used in descriptive statistics to......

...Statistics in Business QNT/351 Aug 21, 2013 Edward Balian Statistics Investopedia defines statistics as a type of mathematical analysis involving the use of quantified representations, models and summaries for a given set of empirical data or real world observations. Statistical analysis involves the process of collecting and analyzing data and then summarizing the data into a numerical form. ("Investopedia", 2013) Types and Levels Descriptive statistics, inferential statistics, ratio-level data, interval- level data, ordinal-level data, and nominal-level date are some types and levels of statistics. Descriptive statistics utilizes numerical and graphical methods to look for patterns in a data set, to summarize the information revealed in a data set, and to present the information in a convenient form. Inferential statistics utilizes sample data to make estimates, decisions, predictions, or other generalizations about a larger set of data. Business decision making When it comes to the role of statistics in business decision-making it is applied in many ways in terms of consumer preferences or even financial trends.   For example, managers across any type of business formulate problems, they decide on a question relating to the problem and then form a statistical formulation of the question is used to determine answers to all of the above.   An example of a business question may be how many calls are......

...Statistics in Business QNT/351 Statistics in business The purpose of this essay is to examine the purpose of statistics in business. Our text, Lind (2011) defines statistics as “The science of collecting, organizing, presenting, analyzing, and interpreting data to assist in making more effective decisions” (p.5). Types and levels of statistics There are two major types of statistics, descriptive and inferential. Descriptive statistics is defined by Lind (2011) as “methods of organizing, summarizing, and presenting data in an informative way” (p.6). An example of descriptive statistics would be a high school report showing that it had 300 graduates in 1990 and 450 graduates on 1991. The information that they provided described the amount of graduates that they had for each year. Inferential statistics is defined by Lind (2011) as “the methods used to estimate a property of a population on the basis of a sample” (p.7). If the same high school sent out a report showing the graduate numbers for 1999- the present to estimate the number of graduates that they would have for this school year, those statistics would be inferential because they are used to estimate future outcomes. There are four levels of statistical data: nominal, ordinal, interval and ratio. The nominal level deals with qualitative variables such as colors and blood types that can only be counted and classified. Ordinal data measurement is a variable rating system that ranks data......

Res 342 Week 2 Team Paper

...µ ≤ 50%. Team C will utilize the five-step hypothesis test on the CIA Global Demographics Data Set to accept or reject the null hypothesis as explained below. Five-Step Hypothesis Test Step 1 Step one of the five step hypothesis is to state the research problem in question form. In this case, I will define what will be tested and identify what variable will be used in the data collection. My hypothesis is: Do more than 50% of the population of both European Union countries and G-20 countries live past the age of 60? Step 2 During step two of the process, both the null and alternate hypotheses are recognized in both verbal and numerical form. The null hypothesis is that greater than 50% of the European Union and G-20 countries live past the age of 60.. This creates an alternative hypothesis that less than 50% of the European Union and G-20 countries die before the age of 60.. H0: µ = > .50 H1: µ NE > .50 alpha = .05 Step 3 The third step of hypothesis testing is to calculate a statistic analogous to the parameter indicated by the null hypothesis. Due to the sample size of 62 countries, the Z-test will be utilized to calculate the test statistic. The x bar is equal to the sample mean of 6.55 and the standard error of x bar is 1.83. Z= x bar - µ...

Simulation with Arena

...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......

Critical Values

...itical values and p values Determination of critical values Critical values for a test of hypothesis depend upon a test statistic, which is specific to the type of test, and the significance level, , which defines the sensitivity of the test. A value of = 0.05 implies that the null hypothesis is rejected 5% of the time when it is in fact true. The choice of is somewhat arbitrary, although in practice values of 0.1, 0.05, and 0.01 are common. Critical values are essentially cut-off values that define regions where the test statistic is unlikely to lie; for example, a region where the critical value is exceeded with probability if the null hypothesis is true. The null hypothesis is rejected if the test statistic lies within this region which is often referred to as the rejection region(s). Critical values for specific tests of hypothesis are tabled in chapter 1. Information in this chapter This chapter gives formulas for the test statistics and points to the appropriate tables of critical values for tests of hypothesis regarding means, standard deviations, and proportion defectives. P values Another quantitative measure for reporting the result of a test of hypothesis is the p-value. The p-value is the probability of the test statistic being at least as extreme as the one observed given that the null hypothesis is true. A small p-value is an indication that the null hypothesis is false. Good practice It is good practice to decide in advance of the test how......

Statistics in Business

...Statistics in Business QNT/275 June 29, 2016 Statistics in Business According to "Define Statistics At Dictionary.com the science that deals with the collection, classification, analysis, and interpretation of numerical facts or data, and that, by use of mathematical theories of probability, imposes order and regularity on aggregates of more or less disparate elements. Quantitative vs. Quantities There are two general types of data. Quantitative data is information about quantities; that is, information that can be measured and written down with numbers. Some examples of quantitative data are your height, your shoe size, and the length of your fingernails. Speaking of which, it might be time to call Guinness. You've got to be close to breaking the record. Qualitative data is information about qualities; information that can't actually be measured. Some examples of qualitative data are the softness of your skin, the grace with which you run, and the color of your eyes. However, try telling Photoshop you can't measure color with numbers. Here's a quick look at the difference between qualitative and quantitative data. The age of your car. (Quantitative.) The number of hairs on your knuckle. (Quantitative.) The softness of a cat. (Qualitative.) The color of the sky. (Qualitative.) The number of pennies in your pocket. (Quantitative.) Remember, if we're measuring a quantity, we're making a statement about quantitative data. If we're describing qualities, we're making a...
