Filtering and then counting distinct values
- by Deon
This is for Excel: I've been tasked with counting distinct records after I have filtered the data. I have 330 rows with column A containing the 'name' and in Column B I have the name of a test that was done for each 'name', which each 'name' could have taken several iterations of the same test. The test results are in Column C.
Col A -Student Col B -Exam Col C - Grade
Student 1 Exam 1 .80
Student 2 Exam 1 .50
Student 3 Exam 1 .90
Student 2 Exam 1 .75
Student 4 Exam 1 .90
Student 5 Exam 1 .55
Student 2 Exam 2 .90
Student 1 Exam 2 .90
.... .... ...
If I filter col B for Exam 1, I want to count the unique number of students that have taken Exam 1.
