I have a dataset of marks of 6 students - A, B, C, D, E, F, G for 30 subjects each.
|Subjects||Student A||Student B||Student C||....|
|... 30 subjects|
The marks are mostly around 50 to 70, rarely rising to 80 or 90.
I wish to determine :
- which students are significantly best/worst
- in which subject students perform better
I want to achieve these inferences using statistical testing, and validate the results with p-value.
Which statistical test should I use for this purpose? Should I be using t-test or ANOVA or some other test? How should I formulate the problem and format the data to use such a test?
I am new to this subject, so kindly pardon my naiveness. A simplified yet detailed help would be highly appreciated.
