Assay validation: All bioassay and potency estimates should be given with the precision of these estimates. For bioassay the main measures of precision are:
- Standard deviation
- Standard error of the mean
- Coefficient of variation
- 95% confidence limits
It is the responsibility of authors to provide data that have reproducible results and are not found due to random variables. Though no steadfast rules apply, researchers should strive to conduct at least three trials that display similar results. Appropriate statistical methods should be used to test the significance of differences observed in results.
