1. Glade Manual – Chapter 6 1 “COUNTIF” function: - “COUNTIF” function counts the number of cells within a range that meet the given condition - In Excel: “=COUNTIF(range, criteria)” - adds one to a running count every time the criteria matches the value in the range output data worksheet Range of cells you want to evaluate criteria COUNTIF EECS 1520 -- Computer Use: Fundamentals

2. Glade Manual – Chapter 6 2 Recall: “LOOKUP” function: - In Excel: “=LOOKUP(lookup_value, lookup_vector, result_vector)” - There are 3 items need to be referred to. Original data Result Lookup table worksheet Length of lookup_vector = length of result_vector output data worksheet EECS 1520 -- Computer Use: Fundamentals

3. Glade Manual – Chapter 6 3 “SUMIF” function: - “SUMIF” function returns the SUM of a number of cells if the criteria is met - In Excel: “=SUMIF(range, criteria, sum_range)” - criteria is often text output data worksheet Range of cells you want to evaluate Actual cells to sum EECS 1520 -- Computer Use: Fundamentals

4. Glade Manual – Chapter 6 4 “MATCH” function: - An array is a row or column of numbers - “MATCH” function returns the position of an item in an array that matches a specified value - In Excel: “=MATCH(lookup_value, lookup_vector, match_type)” - match_type = 0 for exact match output data worksheet EECS 1520 -- Computer Use: Fundamentals

5. Glade Manual – Chapter 6 5 “MATCH” function: - Example: If the range C5:C10 contains the values: 5,8,9,10,12 Then the formula: MATCH (10,C5:C10,0) = 4 Because 10 is the fourth element in the array starting from the left EECS 1520 -- Computer Use: Fundamentals

6. Glade Manual – Chapter 6 6 “VLOOKUP” function: - “V” stands for vertical - “VLOOKUP” function returns a value in the same row from a column you specify - In Excel: “=VLOOKUP(lookup_value, table_array, col_index_num)” - col_index_num is the column number in table_array. It can be computed, using MATCH for example, and selects column that acts as the equivalent of the result_vector in LOOKUP output data worksheet EECS 1520 -- Computer Use: Fundamentals

7. Glade Manual – Chapter 6 7 “INDEX” function: - returns the value in a specified cell within an array - In Excel: “=INDEX(array, row_num, column_num)” -arrayis a range of cells or an array constant -row_num an integer that selects the row in array -column_numan integer that selects the column in array 1 2 3 4 5 row_num 12345 column_num 6 EECS 1520 -- Computer Use: Fundamentals
