A nice easy way to determine the viability of the experiment is to look at the "Adjusted R-Squared Value."

This tells you the amount of variation in experiment results is explained by the model.

Anything below .5 means the model is worse than flipping a coin. 1 means the model perfectly explains the outcome.
