# Kolmogorov-Smirnov test with dependent data

Let's say, I have 100 students, each of them have 2 scores: reading score and writing score, so basically I will have 2 vectors with the length of each is 100.

I want to test the distribution of reading score and writing score are the same or not, so I want to use Kolmogorov-Smirnov test, but is it okay to run the test with dependent data?

• Welcome to our site! I've removed the reference to R in the title, because your question is really completely software-agnostic - it's about the underlying statistical issue of whether the procedure is valid.. – Silverfish Nov 4 '15 at 15:58
• Did you find a way to test the distributions for these paired dependent samples? I am facing the same problem and not sure how to proceed. – Confounded Apr 13 '18 at 10:10
