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]
