The sample sizes used were adequate to determine mean relative condition factors with an accuracy of 1-2% for each species studied. This was sufficient to test the hypothesis that oyster overharvesting had lead to reduced fish condition. Our annual sample sizes were also much larger than a USGS study that also yielded statistically significant results using a very similar method.

In most cases the small uncertainties in relative condition factors yielded p-values below 0.001, indicating good statistical significance. (See table 2 in the paper.)
