I've conducted this linear model, and I received an F-value of 0.05 for the treatment with a P-value of 0.823.

I know that a p-value greater than 0.05 means that the stats are not statistically significant, however, what does a low F-value mean?

*In case it's important, I obtained an R-sq score of 90.58%, R-sq(adj) of 90.52% and R-sq(pred) of 90.39%.
