...statistics students, have access to SPSS and Minitab so in most cases these exercises provide specific instructions for these two packages. We have also included instructions for Excel 2007. While we are cognizant of the issues with using Excel for statistical analyses, we also realize its simplicity for basic functions such as graphing, and we use it in our classes along with Minitab and SPSS because we feel that business students should be proficient in its use. We used SPSS version 15, Minitab version 15, and Excel 2007 to write the following instructions. If your students will be using other versions of these softwares or if you prefer that your students use different statistical software, you will need to edit the instructions accordingly before distributing to your students. Exercise 1: Data Retrieval and Graphing Learning Objectives: 1. Locate and retrieve data from a web site. 2. Place retrieved data into Excel and format appropriately. (This step is recommended because the format from the website is not easily imported directly into SPSS and Minitab). 3. Create and format a time series plot in SPSS, Minitab, Excel or other software. Instructions for the students: For this exercise you will use movie box office data found at http://www.the-numbers.com/. You will locate data for a specific movie, bring the data to Excel to format it, and then create a time series plot using SPSS, Minitab, Excel or other software. 1. Go to http://www.the-numbers.com/ and click...

...Keller Graduate School of Management Applied Managerial Statistics (GM533) Course Project Case Study: Grocery Bags data gathered and written by ME Applied Managerial Statistics GM533 Instructor: XX I. Executive Summary For this research I decided to develop my own case study and collect all the data myself. The data file named “Grocery Bag Study” (separate attachment), contains observations on 33 sample groups with a variation of 8 different characteristics (see table below). These characteristics include ethnicity, number of adults and minors in household, the number of bags collected weekly, the number of bags they recycle or reuse, the use of reusable fabric shopping bags, how many they throw away and the sex of the adults in the household. The totals for the bags are shown in the table below (Table A.1). For the sake of this study, I am going to combine the paper and plastic together because I want my dependent variable to be the number of bags recycled each week. I want to determine if the independent variables affect the recycle rate and which ones affect it the most, which can be eliminated and what my conclusions will be. II. Calculations This file was used to prepare a report on the influence of various options on grocery bags collected each week and to relay how this information could be used to determine the recycle rates (y). Statistical analysis by Hypothesis Testing and Multiple Regression Analysis was performed on the collection of grocery...

...CHAPTER 1 INTRODUCTION The machining conductive as well as nonconductive advanced engineering materials such as glass, ceramics, quartz, granite and composite materials are difficult to machine by usual process. These materials are having wide range of applications in the field of automobile, aerospace and defense field. So processing of these materials is necessary with easy and economical way. Hence Hybrid Machining Process (HMP’s) like ECSM is evolved and is shown in fig1.1. ECSM is the combination of ECM and ESM process, Electro Chemical Machining (ECM) and Electro Spark Machining (ESM) can machine only electrically conductive materials and these two are mot preferable for machining non-conducting and partially conducting advanced materials....
