4. with Microsoft Excel 2007 Comprehensive 1e© 2008 Pearson Prentice Hall4 Create Text Functions Functions are built-in formulas that complete tasks quickly. Functions are usually used for complex mathematical calculations. They are also used for formatting purposes.

5. with Microsoft Excel 2007 Comprehensive 1e© 2008 Pearson Prentice Hall5 Create Text Functions Text functions, such as the TRIM and PROPER functions, format text or add text to a cell. The PROPER function capitalizes the first letter of each word in a cell entry. The TRIM function removes all spaces from text except for single spaces between words.

7. with Microsoft Excel 2007 Comprehensive 1e© 2008 Pearson Prentice Hall7 Create Statistical Functions Statistical functions provide statistical analysis of a worksheet. The median is the value at the midpoint of a series of numbers. The mode is the value that occurs the most often in a list of numbers.

8. with Microsoft Excel 2007 Comprehensive 1e© 2008 Pearson Prentice Hall8 Create Statistical Functions After you type an = (equal sign) and the beginning letters of a function, Excel displays a dynamic list of valid functions. List of function choices

9. with Microsoft Excel 2007 Comprehensive 1e© 2008 Pearson Prentice Hall9 Create Statistical Functions The COUNT function counts the number of cells in the selected range that contain numeric values. The COUNTA function counts the number of cells in the range that are not empty.

10. with Microsoft Excel 2007 Comprehensive 1e© 2008 Pearson Prentice Hall10 Insert Date and Time Functions Date and time functions can be static or volatile. A static date or time remains the same and does not change. A volatile date or time is updated each time the worksheet is used.

11. with Microsoft Excel 2007 Comprehensive 1e© 2008 Pearson Prentice Hall11 Insert Date and Time Functions The TODAY function returns the current date. Each time the worksheet is opened, the TODAY function recalculates so the current date displays. –Click the Formulas tab, and in the Function Library group, click the Date and Time button. From the displayed list click TODAY.

12. with Microsoft Excel 2007 Comprehensive 1e© 2008 Pearson Prentice Hall12 Logical functions test a logical comparison between expressions. They determine whether the conditions are true or false. Create Logical Functions and Insert a Comment

13. with Microsoft Excel 2007 Comprehensive 1e© 2008 Pearson Prentice Hall13 The AND function tests two or more arguments to see whether they are true or false. –Returns TRUE if all arguments are true. –Returns FALSE if any argument is not true. The OR function tests two or more arguments to see whether they are true or false and returns TRUE when any one of the arguments is true. Create Logical Functions and Insert a Comment

14. with Microsoft Excel 2007 Comprehensive 1e© 2008 Pearson Prentice Hall14 Create Logical Functions and Insert a Comment Comments can provide additional information that explains the data in a worksheet. A comment is a remark that is attached to a specific cell but does not display with the worksheet. An indicator alerts the user that a comment is attached to the cell.

15. with Microsoft Excel 2007 Comprehensive 1e© 2008 Pearson Prentice Hall15 Printing comments: –Comments can be printed as they are displayed. –Or they can be printed as text at the end of the worksheet. Create Logical Functions and Insert a Comment

17. with Microsoft Excel 2007 Comprehensive 1e© 2008 Pearson Prentice Hall17 Insert Financial Functions Excel provides more than 50 financial functions. Three functions that are frequently used are: –Future value: FV (rate, periods, payment) –Payment: PMT (rate, periods, loan amount) –Present value: PV (rate, periods, payment)

19. with Microsoft Excel 2007 Comprehensive 1e© 2008 Pearson Prentice Hall19 Create What-If Analysis with Goal Seek Goal Seek is one of Excel’s “what-if” analysis tools. It’s used to find a specific value for a cell by adjusting the value in another cell.

20. with Microsoft Excel 2007 Comprehensive 1e© 2008 Pearson Prentice Hall20 Create What-If Analysis with Goal Seek To use Goal Seek: –Select the Data tab. – In the Data Tools group, click the What-If Analysis button. –In the displayed list, click Goal Seek.
