...QNT 351 August 27, 2014 Henry Jacobs In this report we will revise, summarize, and present our updated data for BIMS case study review. Analyzing the descriptive statistics helps our team breakdown the basic features of quantitative data results from the survey. However, we do not want to risk the chance of distorting our original findings, but use these statistics to analyze the comparisons of answers from employees and departments. Utilizing the central tendency which are three measures: mean, mode, and median allows us to give senior management raw data to make better decisions with. Measures of Variability findings enables us to differentiate results from BIMS surveys which differs from their mean. Our overall recommendation and analysis will be given to senior management within this paper off the current raw data. Data Collected The type of data collected in the survey conducted was quantitative as the data collected in the surveys was expressed numerically. Some of the questions were qualitative however the responses given were provided based on a numerical response. The survey had employees’ answer the question provided based on a scale 1-5, one being very negative and five being very positive. The data collected was later coded and entered into a spreadsheet by Debbie’s office support staff however; some errors existed when keying in the wrong number for the response provided and inputting zeros when the option was not available to employees, zero indicated no...

...Statistics By Rafael Mulero October 14, 2015 QNT 310 Robert Grauer Statistics Statistics can be defined as the science of data that involves organizing, classifying, collecting, interpreting, summarizing, and analyzing numerical information. The types of statistics consist of descriptive and inferential statistics. Descriptive statistics is the use of graphical and numerical methods that locate patterns in data, by doing this it summarizes the data collected, and presents the information in a simplified form. With inferential statistics it uses the sample data to make predictions, decisions, estimates or other generalizations about a larger collection of data. There are other two classifications of statistics and they are qualitative and quantitative. When measurements cannot be measured on a regular numerical scale this is referred to as qualitative data. Qualitative data can only be classified into one of the groups of categories. When data is recorded on a naturally occurring numerical scale is quantitative data. Statistics plays a major role in business decision making. Many companies use statistics to determine whether they’re going to keep a product or service on the market. Also, when making potential decisions when trying to introduce a new product to the market. Companies don’t only use statistics for product or services, they also use it for determining the demographics in the area. They critically assess the data collected and try to generate or produce the...

...Statistics in Business QNT 351 July 21, 2014 Statistics In Business Statistics is a type of mathematical analysis that involves the use of qualified models, summaries, and representations for a given set of empirical data or real world observations (Investopedia, 2014). Levels and Types of Statistics There are two different levels of statistics, descriptive and inferential statistics. Descriptive statistics involves methods of displaying, organizing, as well as describing data using graphs, tables, and summary measures. Inferential statistics describes the population that is based on the sample results. While descriptive and inferential statistics are the main levels; however there are different levels of measurement that is involved in statistics, that being said, there are four levels of measurement. Those levels include ordinal, nominal, ratio, and interval data. Each of these different measurements has different goals, which receives different results in surveys. The Goal of Statistics in Business Decisions Statistics are important when making decisions throughout a company, because businesses statistics that are analyzed properly will help to provide an established market analysis as well as research of competitors in the market. When the results of the statistical analysis are reported correctly, it helps companies to prepare for future as well as current plans based off of the information that is being research.

...Hypothesis Reflection Learning Team A: Kala Chavez, Jessica Gonani, Stacie Knauss, Michael Orcutt, and Troy Stodard QNT 351/Statistics for Business and Economics June 17, 2014 Don Silva Hypothesis Reflection This week Learning Team A is tasked with discussing three parts to hypothesis research. These objectives included evaluating the steps to test a research hypothesis, compare the means of two or more groups, and calculating the correlation between the two variables. By discussing these three objectives, team A will gain a better understanding of how the objectives are associated with statistical analysis. Research hypothesis Testing a theory or hypothesis sounds like an easy task but it is not. There are many steps to testing a research hypothesis. The five steps of hypothesis testing are (The University of North Carolina at Chapel Hill, 2012): 1. Stating the research question or questions 2. Specifying the null and alternative hypothesis involved 3. Calculating the test statistics 4. Computing the probability of test statistics or the rejection region 5. Stating the conclusions The first step, stating the research question, will clearly define and identify the research question. The population of interest, hypothesized values, and the parameters of the variables are clearly stated. Next is to state the hypothesis of at least two possible outcomes. These are the null and alternative hypothesis. The null hypothesis states that nothing will...

...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 according...

What is their significance in research? Explain with examples. Independent variables are the variables that are manipulated to then analyze the effect on the dependent variable. Although, there is not necessarily manipulation of the independent variable but allows for breaking them into groups that fit into specific properties for the study. An example I found to explain this a little clearer is a study of white cell count between the two genders. There is not a manipulation, but the independent variables are male and female and the dependent variable (what is measured) is the white blood cell counts of the genders (StatSoft Electronic Statistics Textbook, 2012). An example from a previous class would be studying childhood obesity and the relationship to fast-food restaurants close to their school. The independent variable would be the fast-food restaurant in proximity to the school and the dependent variable would be the classifications of the children (normal weight, overweight, obese). The important of dependent and independent variables is the ability to study if and/or how much of an effect the independent variable has on the dependent variable. In the example I provided...

...Ballard Integrated Managed Services, Inc., Part 2 Data Collection QNT/351 Quantitative Analysis for Business February 25, 2013 University of Phoenix When explain the central tendency and how it relates to this survey. The measures of central tendency are the set of measurements–that is, the tendency of the data to cluster, or center, about certain numerical values. Also central tendency contains three different parts. When calculating the central tendency, you have to calculate the mean, which is the most common measure of central tendency, acts as a balance point, and is affected by extreme values (outliers). The mean is calculated by taking raw data (a group of numbers), adding them up for a total, and then dividing that total by amount of numbers within the group ( ex: raw data: 3,4,5. 3+4+5=12, then 12/3= 4. The mean equals four). The median, which is the middle value in ordered sequence (If this value is odd, middle value of sequence If this value is even, average of 2 middle values), is not affected by extreme values, position of median in sequence, and the positioning point = n+1/2. The median is calculated by taking the raw data and putting it in ascending order, with the middle number being the mean (odd ex: raw data: 1,5,3,2,4,= ordered: 1,2,3,4,5= position point= 3 median= 3) (even ex: raw data: 6,3,1,4,2,5, Ordered: 1,2,3,4,5,6, position point= 3.5 median= 3.5). And finally, calculate the mode, which is...
