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”
- table_array: the range or boundary of your table(excluding headings)
- 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)
