Microsoft® Excel® Lookup Functions Description: •Searches the first column of a range of cells, and then returns a value from any cell on the same row of the range. Remarks: • The values in the first column of table_array can be text, numbers, or logical values. •Uppercase and lowercase text are equivalent. • If range_lookup is TRUE, the values in the first column of table_array must be placed in ascending order. • If range_lookup is TRUE or omitted, an exact or approximate match is returned. • If range_lookup is FALSE, an exact match will be attempted, sorting not required Microsoft® Excel® Lookup Functions Errors: #VALUE! – If col_index_num is less than 1 #REF! – If col_index_num is greater than the number of columns in the table_array #N/A – If range_lookup is FALSE and an exact match cannot be found #N/A – If lookup_value is less than the smallest value in the first column of table_array Microsoft® Excel® Lookup Functions (1) =VLOOKUP(C11*2, $B$8:$G$24, G18/E6, TRUE) (1) =VLOOKUP(C11*2, $B$8:$G$24, G18/E6, TRUE) =VLOOKUP(44*2, $B$8:$G$24, G18/E6, TRUE) (1) =VLOOKUP(C11*2, $B$8:$G$24, G18/E6, TRUE) =VLOOKUP(44*2, $B$8:$G$24, G18/E6, TRUE) =VLOOKUP(88, $B$8:$G$24, G18/E6, TRUE) (1) =VLOOKUP(C11*2, $B$8:$G$24, G18/E6, TRUE) =VLOOKUP(44*2, $B$8:$G$24, G18/E6, TRUE) =VLOOKUP(88, $B$8:$G$24, G18/E6, TRUE) (1) =VLOOKUP(C11*2, $B$8:$G$24, G18/E6, TRUE) =VLOOKUP(44*2, $B$8:$G$24, G18/E6, TRUE) =VLOOKUP(88, $B$8:$G$24, G18/E6, TRUE) =VLOOKUP(88, $B$8:$G$24, 66/E6, TRUE) (1) =VLOOKUP(C11*2, $B$8:$G$24, G18/E6, TRUE) =VLOOKUP(44*2, $B$8:$G$24, G18/E6, TRUE) =VLOOKUP(88, $B$8:$G$24, G18/E6, TRUE) =VLOOKUP(88, $B$8:$G$24, 66/E6, TRUE) =VLOOKUP(88, $B$8:$G$24, 66/11, TRUE) (1) =VLOOKUP(C11*2, $B$8:$G$24, G18/E6, TRUE) =VLOOKUP(44*2, $B$8:$G$24, G18/E6, TRUE) =VLOOKUP(88, $B$8:$G$24, G18/E6, TRUE) =VLOOKUP(88, $B$8:$G$24, 66/E6, TRUE) =VLOOKUP(88, $B$8:$G$24, 66/11, TRUE) =VLOOKUP(88, $B$8:$G$24, 6, TRUE) ISERROR =ISERROR(value) ISNA =ISNA(value) Syntax: =ISERROR(value) Arguments: •value Required The value that you want tested Microsoft® Excel® Information Functions Description: •Returns TRUE if value refers to any error value: •#N/A #VALUE! #REF! •#NUM! #NAME? #NULL! #DIV/0!

Microsoft® Excel® Lookup Functions Description: • Returns the value of an element in a table or an array, selected by the row and column number indexes. Remarks: • If both the row_num and column_num arguments are used, INDEX returns the value in the cell at the intersection of row_num and column_num.

Errors: #N/A – If MATCH is unsuccessful in finding a match Microsoft® Excel® Lookup Functions Value Behavior Restrictions 1 MATCH finds the largest value The values in the that is less than or equal to lookup_array argument lookup_value. must be placed in ascending order. 0 MATCH finds the first value that is exactly equal to lookup_value. -1 MATCH finds the smallest value that is greater than or equal to lookup_value. None The values in the lookup_array argument must be placed in descending order. Default Microsoft® Excel® Lookup Functions Microsoft® Excel® Lookup Functions Description: •A combination of INDEX and MATCH can be used as a form of table lookup. •It is similar to the VLOOKUP and HLOOKUP function but more flexible. •It is usually of the form: =INDEX(some_array, MATCH(some_value, some_array, criteria), [MATCH(some_value, some_array, criteria)]) Microsoft® Excel® Information Functions How would you find the count of oranges using INDEX and MATCH? =INDEX(A1:B5,MATCH("Oranges",A1:A5,0),MATCH ("Count",A1:B1,0)) OR =INDEX(B1:B5, MATCH("Oranges",A1:A5,0)) Microsoft® Excel® Information Functions • Information Functions ISERROR ISNA ISERROR =ISERROR(value) ISNA =ISNA(value) Syntax: =ISERROR(value) Arguments: •value Required The value that you want tested Microsoft® Excel® Information Functions Description: •Returns TRUE if value refers to any error value: •#N/A #VALUE! #REF! •#NUM! #NAME? #NULL! #DIV/0!

All databases contain one or more of these. _______ retrieve and process your data. They can combine data from different tables, update your data, and perform calculations on your data. _____ control data entry and data views. They provide visual cues that make data easier to work with. _______ summarize and print your data. They turn the data in your tables and queries into documents for communicating ideas. To distinguish one record from another, tables can contain a primary key field. ◦ The primary key is an identifier—such as a part number, a product code, or an employee ID—that's unique to each record. ◦ The primary key should be a piece of information that won't change frequently. ◦ When tables relate, the primary key of one table becomes a foreign key of the other table. Goal Seeking function Can work through multiple scenarios Can have Data tables Example: ◦ Find the interest rate that is needed to finance $25,000 car over 5 years (60 months) with a payment no more than $450.
