In Business Series © Prentice Hall Logical Functions IF  IF Functions  Nested IF Functions

In Business Series © Prentice Hall 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]

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

In Business Series © Prentice Hall 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

In Business Series © Prentice Hall 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 < display “Low”  > display “Spoil Risk”  Between and display “OK”

In Business Series © Prentice Hall 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

In Business Series © Prentice Hall 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.

In Business Series © Prentice Hall 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

In Business Series © Prentice Hall 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

In Business Series © Prentice Hall 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.

In Business Series © Prentice Hall 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.

In Business Series © Prentice Hall 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

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

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

In Business Series © Prentice Hall 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

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