You are all very smart.
I just have a quick question. I have two events--(1) 1st year, 2nd year,
3rd year and 4th year registration records of some high school students and
(2) students ever participating in some science club during their high
school years.
Can we correlate (1) with (2) or vice versa?
The interest is the impact of science club on high school graduation and
registration. However, we don't know when the students participated in the
science club at all.
We can definitely correlate (2) with high school graduation. Not sure
about correlating (1) with (2)--very hard to justify because of the time
sequence.
Thanks. | r*****t

结果才是关键。你可以发问卷调查学生是不是参加club。 |
