Lecture 5

Reference Functions

CSE 2111 Lecture 5-Reference Functions

Finds an entry from a vertical array based on a criteria

=VLOOKUP(lookup_value,table_array,col_index_num,[range_lookup])

• lookup_value: criteria to lookup or “match”

• col_index_num: the column number in your range that contains the corresponding data

• range_lookup:

• True: Finds the exact match or the next lower value in your table array

• False: Finds an exact match in your table array

CSE 2111 Lecture 5-Reference Functions

Finds an exact match or Finds the lowest value without going over

CSE 2111 Lecture 5-Reference Functions

TRUE

• Leftmost column should contain the table range

• Rightmost column should contain the value

• Leftmost column must be in ascending order

• Finds in your table array an exact match or Finds the lowest value without going over

• Beginning value in table array must be the lowest value of a lookup value.

FALSE

• Leftmost column should contain the table range

• Rightmost column should contain the value

• Finds the exact match in your table array

Returns a value you specify if a formula evaluates to an error, otherwise it returns the result of the formula

=IFERROR(value,value_if_error)

VLOOKUP(C8,A\$3\$C\$5,3,FALSE),

VLOOKUP(C8\$A\$3:C\$5,3,FALSE),

(VLOOKUP(C8\$A\$3\$C\$5,2,FALSE)*B8))
