Dear all,
I have problem in analysis data similar to the following:
students X1 X2 X3
1 2 3 1
2 4 5 3
3 1 2 2
4 3 1 4
5 5 4 6
6 6 6 5
I only take 6 individuals, but there are more than that.
Each student is ranked according to Mathematics(X1), Physics (X2) and History (X3).
Does this make sense for each student, to compute the overall performance as (X1+X2+X2)/3, we have ordinal (rank) data and the sum of each variable=21.
Please, is there a general statistical technique to analyze similar data.
Do mean, variance make sense here.
Thanks in advance
Alphonse
