3. Electronic Spreadsheet n Excel is a spreadsheet application for analyzing, organizing, and charting numerical data. Data is entered electronically, so numerical numbers can be updated without time-consuming recalculations or corrections.spreadsheet n Excel can create charts to present your data visually. Data can appear as a a bar, line, XY or pie chart for visual presentation. n Data can be sorted and queried. n Examples: –Fun-N-Sun Sojourn 1st Qtr SalesFun-N-Sun Sojourn 1st Qtr Sales –Inwood: Evaluation of proposed golf sitesEvaluation of proposed golf sites

6. Active Cell Formula Bar Name Box indicates active cell

7. CELLS: The Basic Building Blocks n Each cell has an address, which is determined by its column and row position: –columns are indicated by letters –rows are indicated by numbers n Cells can contain values, labels, or formulas: –labels are the text headings or titles that describe what the numbers represent –values are numbers for calculations –formulas perform calculations

8. Navigate Excel n The basic document file in Excel is a workbook –Up to 255 worksheets –Each worksheet is divided into 256 columns and 65,536 rows –The intersection of a row and column forms a cell, the smallest working section of a worksheet n Navigating a Workbook –Click the sheet tab to activate the worksheet n The current, active cell has a highlighted border, called the cell selector, around it. n Move between cells of a worksheet using either the mouse or the keyboard. n Press Ctrl + Home to return to cell A1

9. Create a Spreadsheet: A Four-step Process To Create A Spreadsheet n Enter the labels that describe the values. Enter the labels n Enter the numbers or values. Enter the numbers or values n Add any formulas needed to calculate results. Add any formulas n Format the entries to make the spreadsheet easy to read and understand.

10. Entering a text label

11. Entering a value/number

12. Entering a formula

13. Use AutoSum n The AutoSum button automatically places the =SUM() function in a selected cell or range. –When a single cell is selected, AutoSum inserts the arguments, then waits for you to confirm the entry. –When a range is selected, AutoSum automatically totals the rows and columns n The AutoSum feature first tries to find values above the selected formula cell, then tries to locate them to the left.

14. AutoFill n The AutoFill feature allows you to enter similar formulas in dozens, or hundreds of cells. n The AutoFill handle is located in the lower right- corner of the cell selector. Dragging it to adjacent cells automatically fills them with a logical progression of formulas, labels, or values.

15. Formulas: A Preview n A formula is used to calculate a result for a defined range of numerical data. n A formula is prefixed with an equal (=) symbol. n Formulas require a set of arguments, and valid mathematical operators. The arguments are the cell addresses. n =C5+C6+C7 is equivalent to =SUM(C5:C7) n Copy a formula does not duplicate it exactly - the relative cell addresses are adjusted when the formula is moved.
