MICROSOFT EXCEL Lecture -4By lec. (Eng.) Hind Basil University of technology Department of Materials Engineering spreadsheet A type of application program which manipulates numerical and string data in rows and columns of cells. The value in a cell can be calculated from a formula which can involve other cells. A value is recalculated automatically whenever a value on which it depends changes. Different cells may be displayed with different formats. Workbook 1. A booklet containing problems and exercises that a student may work directly on the pages. 2. A manual containing operating instructions, as for an appliance or machine. 3. A book in which a record is kept of work proposed or accomplished. Worksheet 1. A sheet of paper with multiple columns; used by an accountant to assemble figures for financial statements. 2. A piece of paper recording work planned or done on a project. What is a COLUMN ? In a spreadsheet the COLUMN is defined as the vertical space that is going up and down the window. Letters are used to designate each COLUMN'S location. In the above diagram the COLUMN labeled C is highlighted. What is a Row? In a spreadsheet the ROW is defined as the horizontal space that is going across the window. Numbers are used to designate each ROW'S location. In the above diagram the ROW labeled 4 is highlighted. What is a Cell? In a spreadsheet the CELL is defined as the space where a specified row and column intersect. Each CELL is assigned a name according to its COLUMN letter and ROW number. In the above diagram the CELL labeled B6 is highlighted. When referencing a cell, you should put the column first and the row second. Basics of a Spreadsheet So let's get started digging into what makes a spreadsheet work. Spreadsheets are made up of 1- columns 2- rows 3- and their intersections are called cells In a spreadsheet there are three basic types of data that can be entered. •labels - (text with no numerical value) •constants - (just a number -- constant value) •formulas* - (a mathematical equation used to calculate) THE BASICS Open Excel. By default, Excel will open a blank workbook that contains three worksheets (spreadsheets). Each box, located in both a column and a row, is called a cell. The Title Bar is located at the very top of the screen. On the Title bar, Microsoft Excel displays the name of the workbook you are currently using. At the top of your screen, you should see "Microsoft Excel - Book1" or a similar name. The Menu Bar is directly below the Title bar and displays the menu. The menu begins with the word File and continues with the following: Edit, View, Insert, Format, Tools, Data, Window, and Help. You use the menu to give instructions to the software. Point with your mouse to a menu option and click the left mouse button. A drop-down menu will appear. You can now use the left and right arrow keys on your keyboard to move left and right across the Menu bar options. You can use the up and down arrow keys to move up and down the drop-down menu. To select an option, highlight the item on the drop-down menu and press Enter. Toolbars Microsoft Excel consists of worksheets. Each worksheet contains columns and rows. The columns are lettered A to IV; the rows are numbered 1 to 65536. The combination of column and row coordinates make up a cell address. For example, the cell located in the upper left corner of the worksheet is cell A1, meaning column A, row 1. Cell E10 is located under column E on row 10. You enter your data into the cells on the worksheet. CELLS Cells can be formatted to help handle various types of data. Right click on a single cell, or a group of cells, and select “Format Cells” from the drop down menu. Brief descriptions of format types can be seen at the bottom of the dialog box. Take a moment to look through the various formatting options. Click cancel when you’re done. Type a number into cell 1A, right click on the cell, and select “Format Cells.” Note that a sample format is shown on the top right of the dialog box. You can adjust the number of decimal places and any preceding symbols. EXCEL HELP WORKING WITH DATA Data that is organized in columns or rows can utilize various formatting methods. Microsoft Excel can import these various types of data. Data can be separated using… Commas (.csv) Tabs or spaces (.txt) Open the file called Staff.csv Resize the columns so that you can see more of the data… Sorting data is sometimes necessary. This data is currently in alphabetical order by last name. Sort it by city instead. Close all spreadsheets. Open the file “sample5yr4cast.csv.” Insert an additional worksheet inside this workbook. Click on Insert/Worksheet. You can rename the new sheet by right clicking on its tab at the bottom, and selecting “Rename” from the menu. Highlight and copy the data from cell B9 through E18. Paste it on the new sheet. Right click on the new worksheet, then select paste from the drop down menu. THE “FILL” FEATURE You can quickly fill in several types of data series by selecting cells and dragging the fill handle or by using the Series command (point to Fill on the Edit menu, and then click Series). CHARTS AND GRAPHS Highlight the data you want to graphically represent. Then click the chart wizard icon on your toolbar You can also launch the Chart Wizard by selecting Insert/Chart. Notice that the Chart toolbar appears when you insert a chart. You can edit the charts properties at any time. FORMULAS AND FUNCTIONS Formulas are equations that perform calculations on values in your worksheet. A formula starts with an equal sign (=). For example, the following formula multiplies 2 by 3 and then adds 5 to the result. =5+2*3 Functions are predefined formulas that perform calculations by using specific values, called arguments, in a particular order, or structure. Functions can be used to perform simple or complex calculations. Looking at cell I19, we can see that there are no special functions associated with the data. Using a simple function can help make regular updates to the data easier. In this case, you can simply click on the Autosum button while cell I19 is selected, and Excel will identify the which cells to include when calculating a total revenue figure for FY2005. Hit enter to lock the sum in. Notice that the function reads: =SUM(I12:I18) The same can be done using a formula, instead of a function. =I12+I13+I14+I15+I16+I17+I18 This long expression helps to show why functions are handy tools. A variety of functions are available. In cell L21, I can use the average function to determine a yearly average for forecasted revenue. fx=AVERAGE(I19:K19) or fx=AVERAGE(I19, J19, K19) or fx=(I19+J19+K19)/3 Click on the small down arrow next to the function symbol (the epsilon). Select “More Functions.” One more thing about formulas and functions: You can utilize data from other worksheets in order to populate cells. The figure in cell c16 is the sum of I19 through k19 on worksheet sample5yr4cast. =SUM(sample5yr4cast!I19:K19) Page Setup dialog box. Click on File/Page Setup. To see all printing options, make sure you select print from the file menu. Clicking on the printer icon on your toolbar will allow to print directly to your default printer with default options.
