Type in Function or
use the Function Wizard
• Function wizard: A short-cut to all the functions in excel (use fx
toolbar button) that walks you through building a function
5
Copying Formulas with
Relative cell referencing
• Automatically adjusts formula cell references when formula
is copied.
6
Copying Formulas with
Mixed cell referencing
Keeps the column or the row reference in the formula the same
when copying the formula (Signified by $)
7
Copying Formulas with
Absolute cell referencing
Keeps the column and the row reference in the formula the same
when copying the formula (Signified by $ in front of column and row)
8
Hard Coding values
Typing in the value in a formula or function instead of a cell reference
• What if service charge changes to 8%?
9
Named Ranges
You can name a cell or a group of cells and use that name in your
formulas.
• Treated as an absolute cell reference
10
COUNTIF FUNCTION
Counts the number of items in a range that meet a specific criteria
=COUNTIF(range, criteria)
• Range: A continuous range
• Criteria: Determines what cells to count
Criteria
Criteria Syntax
Example
Number
Type in number
=COUNTIF(C1:C10,5)
Text
Surround text in quotes
=COUNTIF(E1:E10,”USA”)
Cell Reference
Type in cell reference
=COUNTIF(G1:G10,A2)
“Hard Coded”
Boolean Expression
Surround Boolean expression in quotes
=COUNTIF(I1:I10,”>=5”)
Cell Reference
Boolean Expression
Surround Boolean expression in quotes
and type & before the cell reference
=COUNTIF(K1:K10, “>=” &A5)
Wild Card
Use Asterisk
=COUNTIF(M1:M10,”USA*”)

COUNTIFS FUNCTION
Counts the number of items in a range (using multiple criteria and
multiple ranges) that meet a specific criteria
• All criterion must be true in order for the cell to be counted
=COUNTIFS(criteria_range1, criteria1,[criteria_range2,criteria2], …)
• Criteria_range1: A continuous range
• Criteria1: Determines what cells to count
• Syntax rules the same as COUNTIF
15
16
SUMIF/AVERAGIF FUNCTIONS
Sums the number of items in a range that meet a specific criteria
=SUMIF(criteria_range, criteria,[sum_range])
Averages the number of items in a range that meet a specific criteria
=AVERAGEIF(criteria_range, criteria,[average_range])
• Criteria_Range: A continuous range
• Criteria: Determines what cells to sum
• Sum_Range: If criteria is met, the computer will sum the
corresponding entry in this range
• Same criteria syntax as COUNTIF
• If a sum_range argument is not used, the sum_range will be the
same as the criteria_range

SUMIFS/AVERAGEIFS FUNCTIONs
Sums a range (using multiple criteria and multiple ranges) that meet a
specific criteria
• All criterion must be true in order for the cell to be summed
=SUMIFS(sum_range, criteria_range1,criteria1,[criteria_range2,criteria2], …)
Averages a range (using multiple criteria and multiple ranges) that meet a specific criteria
=AVERAGEIFS(average_range, criteria_range1,criteria1[criteria_range2,criteria2], …)
•
•
•
•
Sum_Range: Range to sum if criterion are met
Criteria_Range1: Range of first criteria
Criteria1: Criteria for range1
Criteria syntax rules the same as COUNTIF
20
21
IF FUNCTION
Checks to see if a condition is true or false. If true one thing
happens, if false another thing happens
• IF this is true, do this, else do this.
=IF(logical test, value_if_true, [value_if_false])
• Logical test must evaluate to true or false
22
23
NESTED IF
• IF this is true, do this, else IF this is true, do this, else, do this.
=if(this = true, do this, else if(this = true, do this, otherwise do this))
• Can be nested up to 64 times.
24
Assume no student
has the same score.
25
IF with a range
26
Using Boolean functions
=AND(logical1, [logical2], …)
• Returns true if all arguments evaluate to true
=OR(logical1, [logical2], …)
• Returns true if at least one argument evaluates to true
=NOT(logical)
• Changes false to true and true to false

VLOOKUP/HLOOKUP
Finds an entry from a vertical array (table) based on a criteria
=VLOOKUP(lookup_value,table_array,col_index_num,[range_lookup])
Finds an entry from a horizontal array based on a criteria
=HLOOKUP(lookup_value,table_array,row_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 finds the closest value in your table array without going over
– False: Finds an exact match in your table array
