3. In Business Series © Prentice Hall 2007 3 Logical Functions IF  IF Functions  Nested IF Functions

4. In Business Series © Prentice Hall 2007 4 Logical Functions  Used to evaluate data and provide output  Output is defined based on logical test  Results will be either true or false  Uses three arguments:  logical_test  [value_if_true]  [value_if_false]

5. In Business Series © Prentice Hall 2007 5 IF Function  Comparison operators  = Equal to  > Greater than  < Less than  <> Not equal to  >= Greater than or equal to  <= Less than or equal to

6. In Business Series © Prentice Hall 2007 6 IF Function (cont.)  Alternate method shown  IF function now calculates the order quantity needed to maintain 10,000 pound target  Results shown are sorted in descending order

7. In Business Series © Prentice Hall 2007 7 Nested IF Functions  Used when the function should display one of many possible outputs  One of four outputs are needed:  < 5000 display “Prod Risk”  > 5000 and < 10000 display “Low”  > 14000 display “Spoil Risk”  Between 10000 and 14000 display “OK”

9. In Business Series © Prentice Hall 2007 9 Logical Functions AND OR  Also used to evaluate data based on logical tests  Can be used independently  Often used in the logical test argument of an IF Function

10. In Business Series © Prentice Hall 2007 10 AND Function  Evaluates data using the same logical test shown in the IF section.  You can enter up to 30 logical tests!  If ALL logical tests are true, the word TRUE will display.  If ANY of the logical tests are false, the word FALSE will display.

11. In Business Series © Prentice Hall 2007 11 AND Function (cont.)  TRUE is displayed in column F that meets ALL three logical tests  FALSE is displayed if the results are false for ANY of the three logical tests  Because of sorting, all TRUE outputs are grouped at the top of the worksheet

12. In Business Series © Prentice Hall 2007 12 OR Function  Major difference from AND Function:  If any logical test is true, word TRUE will be displayed  Is used where the existence of just one criterion is required to trigger a decision

13. In Business Series © Prentice Hall 2007 13 Combining AND, OR, and IF Functions  When combined with IF, output can be controlled (i.e., not TRUE or FALSE).  The example assumes that a customer could receive one of two discount coupons.  50% off for year or longer customers who has not made a purchase in the last 12 months.  10% off for all others.

14. In Business Series © Prentice Hall 2007 14 Combining (cont.)  Combining the IF and OR Functions  The example assumes that a customer could receive one of two discount coupons.  25% discount for customers who have either been making purchases for more than 2 years or have spent more than $1,000 in the past year.  10% off for all others.

16. In Business Series © Prentice Hall 2007 16 Lookup Functions  Used for assembling data in a worksheet  Data normally comes from several sources or pick specific points from larger datasets  Two lookup functions will help you assemble data  VLookup  HLookup

17. In Business Series © Prentice Hall 2007 17 VLookup Function  Used mostly to display data from one worksheet or workbook into another

18. In Business Series © Prentice Hall 2007 18 VLookup Function (cont.)  Four arguments  lookup_value  table_array  col_index_num  [range_lookup]

19. In Business Series © Prentice Hall 2007 19 HLookup Function  Used when data is organized across a row instead of down a column  HLookup identical to VLookup except that it looks horizontally and not vertically for a match

20. In Business Series © Prentice Hall 2007 20 HLookup Function (cont.)  The four arguments are identical to those in the VLookup function.  lookup_value  table_array  row_index_num  [range_lookup]
