NESTED IF
• IF functions can be nested
• For example:
– A store gives its employees commission based on
sales
– For sales <= $1000, they earn 5%
– For sales > $1000 and <= $5000, they earn 7.5%
– For sales > $5000, they earn 10%
– IF(sales <= 1000, sales*0.05, IF(sales <= 5000,
sales*0.075, sales*0.10))

LOGICAL FUNCTIONS
• Logical functions accept True and False
values
• AND(logical1, logical2)
– Returns True if logical1 AND logical2 are both
True, False otherwise
• OR(logical1, logical2)
– Returns True if either logical1 OR logical2 is True,
False otherwise
• NOT(logical)
– Returns the opposite of logical. True -> False,
False->True
4
LOGICAL FUNCTION EXAMPLE
• For a class, bonus points are given for
having no absences and also for having
no late assignments
– Show students who got bonus points in both
categories
– Show students who got bonus points for one
category
– Show students who got no bonus points
5
MATCH
• MATCH(lookup_value, lookup_array,
[match_type])
– Looks up the position of lookup_value in
lookup_array
– match_type: 1 finds the largest value <=
lookup_value from an array in ascending
order; -1 finds the smallest value >=
lookup_value from an array in descending
order; 0 finds an exact match for
lookup_value
6
INDEX
• INDEX(array, row_num, [column_num])
– Returns the value in array in the row specified
by row_num
– If the array range has multiple columns, you
can specify which column you want to index
by specifying the column_num argument
7
MATCH/INDEX EXAMPLE
• We have sales per city for a company
• We would like to know
– What are the lowest sales numbers for any
city?
– What is the city of lowest sales?
• To calculate this we will also calculate
– What is the position of the city with the lowest
sales in our list?
8
NESTING FUNCTIONS
GRAPHICALLY
• Open the dialog for your outermost function
• Click the argument box where the nested
function is needed
• Click the Name Box arrow to select the
function you need
• Enter the arguments for the nested function
• Click the name of the outer function in the
formula bar to return to the outer function’s
dialog box
9
ADVANCED FILTERING
• Create a Criterion Range
– Copy the labels from the table and add conditions
for any fields you want to restrict
– Multiple rows of conditions will create an OR filter
• Data->Sort & Filter->Advanced
–
–
–
–
Filter in-place or Copy
Select data range
Select criterion range
Select location if copying
10
DSUM, DAVERAGE, DMAX, DMIN,
DCOUNT
• DSUM(data_range, field_name,
criteria_range)
• Same arguments for the other functions
– data_range specifies the table we want to
aggregate data from
– field_name specifies the label above the
column we would like to aggergate
– criteria_range specifies the range with your
criteria (like advanced filtering)
11
FINANCIAL FUNCTIONS
• IPMT(rate, per, nper, pv)
– Calculates the interest for a specific payment period
• PPMT(rate, per, nper, pv)
– Calculates the principal repayment for a specific
payment period
• CUMIPMT(rate, nper, pv, start_period, end_period,
type)
– Calculates the cumulative interest paid
• CUMPRINC(rate, nper, pv, start_period,
end_period, type)
– Calculates the cumulative principal repaid
12
PV AND FV
• PV(rate, nper, pmt)
– Calculates the present value of future
payments
• FV(rate, nper, pmt)
– Calculates the future value of an investment
13
WHAT-IF ANALYSIS
• What-If Analysis is a process of
experimenting with different variables and
assumptions to observe how they affect
the results of the situation
– We will see examples of one-variable analysis
and two-variable analysis
14
ONE VARIABLE ANALYSIS
• The variable you will be investigating will
be tried for several different substitution
values.
– For example, changing the interest rate on a
loan
– Calculate the desired value for each possible
substitution value
15
SERIES
• Home->Editing->Fill->Series
– Creates series of values you can use as
substitution values
• Step value: distance between values
• Stop value: where you want the series to stop
16
WHAT-IF TOOL
• Data->Data Tools->What-If Analysis->Data
Table
– Select the reference for the cell you want to
replace
• If your series is in rows, use ‘Row input cell’
• If your series in in columns, use ‘Column input cell’
– Click Ok to complete the table
