How can I count deviations between two rows?
Here's what I'm trying to do:
1 Test Question 1 2 3 4 5 6 ... 2 Answers Key A C A B D B ... # of Right Answers 3 Student 1 A D A B D C ... 4 (Formula would go here to compare current row) 4 Student 2 A C A B D D ... 5 (with Answer Key row & count the right answers) .... How do count the right answers by comparing the answers from each student with the Answer Key in row 2. I want to be able to score the tests by entering in the answers. |

You could employ helper cells located somewhere else on your sheet and
do a sum of those. Using your setup. Column A = Student Name: Columns B - G = Test Answers 1 - 6 Lets use AB as your 1st Helper-Cell: AB = IF($B3=$B$2,1,0) AC = IF($C3=$C$2,1,0) AD = IF($D3=$D$2,1,0) AE = IF($E3=$E$2,1,0) AF = IF($F3=$F$2,1,0) AG = IF($G3=$G$2,1,0) ..... .... ... .. Copy formula's down as required. And finally, to total each row of Helper-Cells: Again, lets assume it Column H. H3 = SUM($AB3:$AG3) H4 = SUM($AB4:$AG4) ..... .... ... .. Copy formula's down as required. HTH Mick. |

I want to be able to score the tests by entering in the answers. If the Answer Key is in C2:H2 and the Student1 answers are in C3:H3, then: =SUMPRODUCT(--(C3:H3=$C$2:$H$2)) You can copy that formula down the column. |

=IF(LOOKUP(ROW(A1),$A$2:$A$16,$B$2:$B$16)=C2,"Corr ect","Incorrect") Assuming: Question number is mentioned in A2:a16 Correct answer is mentioned in b2:b16 Student 1 answer is mentioned in D2:d16 Then, Paste this formula in cell e2 |
