Abstract: One popular Additional Mathematics textbook used in Singapore schools introduces "Standardisation of Marks" with a problem. Consider this problem, after being introduced to the concept of mode, median,
mean and standard deviation.
"Suppose in a school preliminary examination, Student D scored 82 marks in Physics and 69 marks in Chemistry. In which subject did he perform better?"
The author goes on to state that, "for realistic comparison of students' abilities in different tests, we have to express the actual scores or the raw scores of the students in another way: we have to take
into consideration the mean score and the standard deviation for the test".
This is interesting as nothing was mentioned about the type of distribution (curve), the sample size nor the term "normal" used. This
paper attempts to look into the validity of the above standardization process and the concept of "standardization of scores".
