统计代写|商业分析作业代写Statistical Modelling for Business代考|Excel, MegaStat, and Minitab for Statistics

In this book we use three types of software to carry out statistical analysis – Excel 2013, MegaStat, and Minitab $17 .$ Excel is, of course, a general purpose electronic spreadsheet program and analytical tool. The analysis ToolPak in Excel includes many procedures for performing various kinds of basic statistical analyses. MegaStat is an add-in package that is specifically designed for performing statistical analysis in the Excel spreadsheet environment. Minitab is a computer package designed expressly for conducting statistical analysis. It is widely used at many colleges and universities and in a large number of business organizations. The principal advantage of Excel is that, because of its broad acceptance among students and professionals as a multipurpose analytical tool, it is both well-known and widely available. The advantages of a special-purpose statistical software package like Minitab are that it provides a far wider range of statistical procedures and it offers the experienced analyst a range of options to better control the analysis. The advantages of MegaStat include (1) its ability to perform a number of statistical calculations that are not automatically done by the procedures in the Excel ToolPak and (2) features that make it easier to use than Excel for a wide variety of statistical analyses. In addition, the output obtained by using MegaStat is automatically placed in a standard Excel spreadsheet and can be edited by using any of the features in Excel. MegaStat can be copied from the book’s website. Excel, MegaStat, and Minitab, through built-in functions, programming languages, and macros, offer almost limitless power. Here, we will limit our attention to procedures that are easily accessible via menus without resorting to any special programming or advanced features.

Commonly used features of Excel 2013, MegaStat, and Minitab 17 are presented in this chapter along with an initial application-the construction of a time series plot of the gas mileages in Table 1.7. You will find that thẻ limited instructions included hêré, alông with thê built-in hêlp féatures ớ all thieê sơftware packages, will serve as a starting point from which you can discover a variety of other procedures and options. Much more detailed descriptions of Minitab 17 can be found in other sources, in particular in the manual Getting Started with Minitab $17 .$ This manual is available as a pdf file, viewable using Adobe Acrobat Reader, on the Minitab Inc. website-go to http://www.minitab.com/en-us/support/documentation/ to download the manual. This manual is also available online at http://support.minitab.com/en-us/minitab/17/getting-started/. Similarly, there are a number of alternative reference materials for Microsoft Excel 2013. Of course, an understanding of the related statistical concepts is essential to the effective use of any statistical software package.

Because Excel 2013 may be new to some readers, and because the Excel 2013 window looks somewhat different from previous versions of Excel, we will begin by describing some characteristics of the Excel 2013 window. Versions of Excel prior to 2007 employed many drop-down menus. This meant that many features were “hidden” from the user, which resulted in a steep learning curve for beginners. Beginning with Excel 2010, Microsoft tried to reduce the number of features that are hidden in drop-down menus. Therefore, Excel 2013 displays all of the applicable commands needed for a particular type of task at the top of the Excel window. These commands are represented by a tab-and-group arrangement called the ribbon-see the right side of the illustration of an Excel 2013 window on the next page. The commands displayed in the ribbon are regulated by a series of tabs located near the top of the ribbon. For example, in the illustration, the Home tab is selected. If we selected a different tab, say, for example, the Page Layout tab, the commands displayed by the ribbon would be different.
We now briefly describe some basic features of the Excel 2013 window:
1 File button: By clicking on this button, the user obtains a menu of often used commands-for example, Open, Save, Print, and so forth. This menu also provides access to a large number of Excel options settings.

For example, when the Home tab is selected (as in the figure), the features, commands, and options displayed by the ribbon are all related to making entries into the Excel worksheet. As another example, if the Formulas tab is selected, all of the features, commands, and options displayed in the ribbon relate to using formulas in the Excel worksheet.
Appendix $1.1$
Getting Started with Excel
3 Quick access toolbar: This toolbar displays buttons that provide shortcuts to often-used commands. Initially, this toolbar displays Save, Undo, and Redo buttons. The user can customize this toolbar by adding shortcut buttons for other commands (such as New, Open, Quick Print, and so forth). This can be done by clicking on the arrow button directly to the right of the Quick Access toolbar and by making selections from the “Customize” drop-down menu that appears.

This notation indicates that we first select the Home tab on the ribbon, then we select Format from the Cells Group on the ribbon, and finally we select Row Height from the Format drop-down menu.

For many of the statistical and graphical procedures in Excel, it is necessary to provide a range of cells to specify the location of data in the spreadsheet. Generally, the range may be specified either by typing the cell locations directly into a dialog box or by dragging the selected range with the mouse. Although for the experienced user, it is usually easier to use the mouse to select a range, the instructions that follow will, for precision and clarity, specify ranges by typing in cell locations. The selected range may include column or variable labels-labels at the tops columns that serve to identify variables. When the selected range includes such labels, it is important to select the “Labels check box” in the analysis dialog box.
