Disclosure: I have an introductory college level of statistical background (but even that was a long time ago).
We put out a survey, essentially asking for value X at a time in the past and value X at the present. We did the same with value Y (i.e., asked what value Y was in the past and what value Y is now in the present). Approximately 100 people were surveyed, and each answered all four questions. A preliminary review of the data shows there is change in Y does not depend on change in X (My terminology may be inexact; I'm trying to say that ∆X does not explain ∆Y). However, my "preliminary review" holds little weight: I need statistical evidence to back it up.
This is where I'm at a loss. How do I show that ∆X does not explain ∆Y? Dtlyng (talk) 03:24, 1 December 2014 (UTC)
What does person month mean? For example, the heart attack is 12 per 1000 person months? — Preceding unsigned comment added by Whereismylunch (talk • contribs) 03:27, 1 December 2014 (UTC)
