Yes.
Find the constant k for each of the 2 r and t values you've gotten by this formula:
k = r/(t^2)

If the k values are not similar (within the limits of experimental accuracy), then the idea is not supported (or conversely, IS supported). When I did this experiment at school, my values did not support it.
Also note that there's no 'standard' answer to this question (a blatant yes or no). It depends on what YOU get from your readings.
