2. 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 CSE 2111 Lecture 4-Countif Sumif etc.

5. CSE 2111 Lecture 4-Countif Sumif etc.

6. 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 CSE 2111 Lecture 4-Countif Sumif etc.

7. CSE 2111 Lecture 4-Countif Sumif etc.

8. 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 CSE 2111 Lecture 4-Countif Sumif etc.

10. CSE 2111 Lecture 4-Countif Sumif etc.

11. 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 CSE 2111 Lecture 4-Countif Sumif etc.

12. CSE 2111 Lecture 4-Countif Sumif etc.

13. 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. CSE 2111 Lecture 4-Countif Sumif etc.

14. 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 CSE 2111 Lecture 4-Countif Sumif etc.

15. CSE 2111 Lecture 4-Countif Sumif etc.

16. 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-thsmallest value in a range • Array: A continuous range • k: The position (from the smallest) in the array (range) CSE 2111 Lecture 4-Countif Sumif etc.

17. CSE 2111 Lecture 4-Countif Sumif etc.

18. 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 CSE 2111 Lecture 4-Countif Sumif etc.
