Best ResponseYou've already chosen the best response.1if out of 64 students, the average score was 82 ... this is not telling us how many of the students got an 82 .. x/64 would be a proportion setup

Best ResponseYou've already chosen the best response.1paired differences would only be used if both sample sizes are the same and the samples are dependent (connected) somehow eg: before and after tests

Best ResponseYou've already chosen the best response.1i think paired data tends to use the same sample group, and compares it like a before and after
