I need to find percentage from two values which are coming from two different population sets that has large difference in population sizes. They are also different in nature. I set is teachers and another set is students.
I have the performance score of 10 schools.
Each schools have filled...
I wanted to have a combined score for a students test.
18 student have written three different tests. First test has 10 maximum marks, second test has 15 maximum marks, third test has 170 maximum marks.
