Comparing values in the same column

I have a table of test scores where each student as a potential 4 scores with different IDs. I need to be able to filter the IDs to find which is the lowest or highest for each student.

 

Example:

Student 1

Test1  50

Test2 40

Test3 30

Test4 20

 

Student 1 lowest score Test4

 

Once I know which test had the lowest score I can compare their score against the passing criteria and determine if they passed or not.

 

Any help would be much appreciated!!

Use MINX to find the lowest score for a student and then you can use FILTER to filter down to that value for the student.

 

For example, if you have

Student,Test,Score

Student1, Test1,20

Student1, Test2,40

Student2, Test1,50

Student2, Test2,20

 

Then you could do something like:

 

VAR __student = MAX([Student])
VAR __table = FILTER(Table,[Student]=__student)
VAR __lowest = MINX(__table,[Score])
RETURN
MAXX(FILTER(__table,[Score]=__lowest),[Test])
