Nested If in Excel

• A nested IF statement says something like...

• "If the answer is yes, do this. If the answer is no do this or this (depending on...“

• Syntax:

• IF( condition1, value_if_true, IF( condition2, value_if_true, value_if_false ))

The LARGE function

26

Description:• Returns the k-th largest value in a data set.

Remarks:• If n is the number of data points in a range, then LARGE(array,1) returns

the largest value.• If n is the number of data points in a range, then LARGE(array,n) returns

the smallest value.

Errors:#NUM! – If array is empty#NUM! – If k ≤ 0#NUM! – If k is greater than the number of data points

=LARGE(array,k)

3rd largest number in the numbers in columns A and B

27

=LARGE(array,k)=LARGE(A2:B6,

3rd largest number in the numbers in columns A and B

28

=LARGE(array,k)=LARGE(A2:B6,3)

3rd largest number in the numbers in columns A and B

29

=LARGE(array,k)=LARGE(A2:B6,3)

3rd largest number in the numbers in columns A and B

The SMALL function

31

Description:• Returns the k-th smallest value in a data set.

Remarks:• If n is the number of data points in a range, then SMALL(array,1) returns

the smallest value.• If n is the number of data points in a range, then SMALL(array,n) returns

the largest value.

Errors:#NUM! – If array is empty#NUM! – If k ≤ 0#NUM! – If k is greater than the number of data points

=SMALL(array,k)

4th smallest number in first column

32

=SMALL(array,k)=SMALL(A2:A10

4th smallest number in first column

33

The HLOOKUP function

36

Errors:#VALUE! – If row_index_num is less than 1

#REF! – If row_index_num is greater than the number of rows in the table_array

#N/A – If range_lookup is FALSE and an exact match cannot be found

OR#N/A – If lookup_value is less than the smallest value in the first

row of table_array

The HLOOKUP function

37

  A B C1 Axles Bearing Bolts2 4 4 93 5 7 104 6 8 11

FormulaDescription (Result)Looks up Axles in row 1, and returns the value from row 2 that's in the same column. (4)

=HLOOKUP("Axles",A1:C4,2,TRUE)

=HLOOKUP("Bearings",A1:C4,3,FALSE)

Looks up Bearings in row 1, and returns the value from row 3 that's in the same column. (7)

=HLOOKUP("B",A1:C4,3,TRUE)

Looks up B in row 1, and returns the value from row 3 that's in the same column. Because B is not an exact match, the next largest value that is less than B is used: Axles. (5)

=HLOOKUP("Bolts",A1:C4,4)Looks up Bolts in row 1, and returns the value from row 4 that's in the same column. (11)

The ISERROR function

Microsoft® Excel® Information Functions

• Returns TRUE if value refers to any error value:

• #N/A #VALUE! #REF! #DIV/0!

• #NUM!#NAME? #NULL!
