[value_if_false]

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 ))

What was the percentage grade you got on your last test? 75%

You got a C

The formula that would go in the yellow box…..

=IF(F42<60%,"Sorry, you failed",IF(F42<70%,"You got a D",IF(F42<80%,"You got a C",IF(F42<90%, "You got a B", "WOW you got an A!!!"))))

The AVERAGEIF function

13

=AVERAGEIF(B2:B5,"<23000")


14

=AVERAGEIF(B2:B5,"<23000")=14000


15

=AVERAGEIF(A2:A5,"<95000")


16

=AVERAGEIF(A2:A5,"<95000")=#DIV/0

23

=COUNTA(A1:A8)=7

The MAX function

24

The MIN function

25

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,


28

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


29

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


List the numbers in descending order:

=5 30

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


33

=SMALL(array,k)=SMALL(A2:A10,4)


List the numbers in ascending order:

233444567

34

=SMALL(array,k)=SMALL(A2:A10,4)


List the numbers in ascending order:

=4 35

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!

The ISNA function

Some More Practice – EXAMPLE 1

Q. In the month with the most rainfall, how much damage did the rain cause?

A. =VLOOKUP(MAX(B2:B13),B2:D13,3)

= $250,000.00

The VLOOKUP function – Example 2

Q. How much total profit was made on the item that costs $40.00?

A. =VLOOKUP(40,C2:F7,4,FALSE)

The HLOOKUP function – Example 2

Q. How many motherboards did they sell?

A. =HLOOKUP(“Quantity”,A1:F9,6,FALSE)

Quiz Questions 1-4• Spend 5 minutes working on questions

1-4 on the handout.

• 1) Assuming the potential profit is calculated by multiplying the profit margin by the # of items on hand, what formula is in I4? Assume you plan on copying the formula in cells I5 through I13.

• =G4*H4

• 2) What is the total potential profit if all menu items on hand are sold?

• =SUM(I4:I13) 45

Quiz Questions 1-4• 3) What is the average menu price for

items >$10?
