# Do two different graphs with similar $R^2$ values show a connection between the data?

With my data (Y and X variables) I have $R^2$ = 0.3736.

I used the data from an article that did the same type of experiment, and made a graph and found their $R^2$ = 0.3706.

I know that the values are very low, but that is all I think I can do with the data. Because both graphs have very similar $R^2$ values, does that mean that there is some sort of connection or similarity between both sets of data?

• Similarity of $R^2$ doesn't of itself imply any kind of connection, no. – Glen_b Dec 29 '13 at 18:46

$Y = \beta_0 + \beta_1X + \epsilon$
