- 1. USE EXCEL FORMULAS TO MANAGE STUDENT GRADES .© Permission is granted to copy, distribute and modify this document as long as you give me credit.
- 2. WORKSHOP OBJECTIVEAfter completion of the workshop, participants will be ableto:• Identify the syntax and operators of an Excel formula• Use SUM(), MAX(), MIN(), SMALL(), COUNTIF(), and AVAREAGE() to perform statistical calculation• Construct an IF() formula to perform computation• Create a look-up table and use VLOOKUP() function to update student letter grade
- 3. OPERATORS OPERATOR MEANING EXAMPLE+ (plus sign) Addition 3+3– (minus sign) Subtraction 3–1 Negation –1* (asterisk) Multiplication 3*3/ (forward slash) Division 3/3% (percent sign) Percent 20%^ (caret) Exponentiation 3^2= (equal sign) Equal to A1=B1> (greater than sign) Greater than A1>B1< (less than sign) Less than A1<B1>= (greater than or equal to sign) Greater than or equal to A1>=B1<= (less than or equal to sign) Less than or equal to A1<=B1<> (not equal to sign) Not equal to A1<>B1: (colon) Range operator, which produces one B5:B15 reference to all the cells between two references, including the two references
- 4. EXCEL FORMULAS AND FUNCTIONS FUNCTION WHAT IT DOESSUM(range) Adds all the numbers in a range of cellsAVERAGE(range) Calculates the average of a range of cellsIF(LogicalTest, TrueValue, falseValue) Checks whether a condition is met, and returns one value if true, and anther value if falseMAX(range) Returns the largest value in a set of values. It ignores logical values and textMIN(range) Returns the smallest value in a set of valuesCOUNT(range ) Counts the number of values (cells containing numbers) in a rangeCOUNTIF(range, criteria ) Counts the number of cells that are the same as a search stringSMALL(range, k) Returns the k-th smallest value in a set of values
- 5. AVERAGE AND WEIGHTED AVERAGE SCORE• Average of a set of scores: • AVERAGE() All cell weighted equally • =AVERAGE(B2:B5)• Weighted Average: • 20% and 40% weight • =(B2+C2+D2)*0.2+E2*0.4
- 6. AVERAGE AND WEIGHTED AVERAGE SCORE A B C D E F G Name Quiz 1 Quiz 2 Quiz 3 Final Total Score Weighted 1 Average 2 Angela 98 91 98 81 =SUM(C2:E2 =B2*0.2+C2 ) *0.2+D2*0.2 +F2*0.4 … Eric 89 78 85 92 5 John 68 67 73 43 6 Average =AVERAGE(B 2:B5) 7 Highest =MAX(B2:B5 ) 8 Lowest =MIN(B2:B5)
- 7. DROPPING LOWEST SCORES• Drop one lowest score =SUM(B2:E2)-MIN(B2:E2)• Drop two lowest score =SUM(B2:E2)-MIN(B2:E2)-SMALL(B2:E2,2)
- 8. TAKING ATTENDANCE• Recording Student Attendance• Displaying Attendance in Another Worksheet A B C D E F G H 1 Name Quiz 1 Quiz 2 Quiz 3 Final Total Absence Adjusted 2 Angela 98 91 98 81 =Attendance!I2 =IF(G2>=3,F2- 30,F2)
- 9. ADJUSTING SCOER• Excel IF() function to adjust student score based on your class policies =IF(Criteria, Value if true, Value if false)• AND() check whether all arguments are true. OR() function checks whether any of the arguments are true.• ISBLANK() check whether a reference is an empty cell and returns true or false• What the hell is this? =IF(AND(A1>B1, NOT(ISBLANK(B1))), AVERAGE(A1, B1), B1)
- 10. LETTER GRADES• VLOOKUP() function looks for a value =VLOOKUP(lookup value, lookup table range, value column) A B C D E F G H I 1 Name Quiz 1 Quiz 2 Quiz 3 Final Total Absence Adjusted Score Grade =VLOOKUP(H2,$A$10:$B 2 Angela 98 91 98 81 368 1 368 $14,2) 3 Debra 72 78 78 97 325 1 325 B … 9 10 0 F 11 240 D 12 280 C 13 320 B 14 360 A
- 11. ANALYSIS TOOLPAK• Microsoft Office Excel add-in• ANOVA• correlation or• t-test
