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(B3:B31,6)
Text Surround text in quotes =COUNTIF(B3:B31,”USA”)
Cell Reference Type in cell reference =COUNTIF(B3:B31,A2)
“Hard Coded” Boolean Expression
Surround Boolean expression in quotes =COUNTIF(B3:B31,”<=5”)
Cell Reference Boolean Expression
Surround Boolean expression in quotes and type & before the cell reference
=COUNTIF(B3:B31, “>” &B2)
Wild Card Use Asterisk =COUNTIF(B3:B31,”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

SUMIF FUNCTION
Sums the number of items in a range that meet a specific criteria
=SUMIF(criteria_range, criteria,[sum_range])
• Criteria_Range: A continuous range• Criteria: Determines what cells to count• 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 FUNCTION
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], …)
• 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

AVERAGEIF and AVERAGEIFS FUNCTION
=AVERAGEIF(criteria_range, criteria,[average_range])Averages the number of items in a range that meet a specific criteria
=AVERAGEIFS(average_range, criteria_range1,criteria1[criteria_range2,criteria2], …)
Averages 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 averaged.

SUMPRODUCT FUNCTION
Multiplies corresponding components in the given arrays, and returns the sum of those products.
=SUMPRODUCT(array1, [array2], [array3], …)
• array1: The first array argument whose components you want to multiply and then add
• The array arguments must be the same dimension• Treats non-numeric cells as 0

LARGE and SMALL FUNCTION
=LARGE(array, k)Returns the k-th largest value in a range
• Array: A continuous range• k: The position (from the largest) in the array (range)
=SMALL(array, k)Returns the k-th smallest value in a range
• Array: A continuous range• k: The position (from the smallest) in the array (range)

RANK.EQ FUNCTION
Returns the rank of a number in a list of numbers
=RANK.EQ(number, ref, [order])
• Number: The number whose rank you want to find• Ref: The Array or range of values to rank• Order: A number specifying how to rank the numbers
– 0 or omitted: Ranks in descending order– 1: Ranks in ascending order
