Basic Statistics: Reciprocal Variable Better Fit?

  1. Nov 29, 2013 #1
    Hello,

    I have some data that I am looking into correlation factors (Pearson). Let's say I have two data sets: X and Y. I have Graph X vs. Y then graph 1/X vs. Y. The reciprocal (1/X) yields a more linear relationship. Why does this occur?

    Thanks in advance!

    Maybe your data has roughly Y~1/X?
    Why do you expect a linear relationship at all?
