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]

IF Function

Comparison operators = Equal to > Greater than < Less than <> Not equal to >= Greater than or

equal to <= Less than or equal

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 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”

Logical FunctionsAND 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 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.

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

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

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.

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.

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 2007 17

VLookup Function

Used mostly to display data from one worksheet or workbook into another

In Business Series © Prentice Hall 2007 18

VLookup Function (cont.)

Four arguments lookup_value table_array col_index_num [range_lookup]

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

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]
