His study consistently found that levels of BPA in people were much lower than the levels required for significant effects.
This doesn't mean that the authors or the journal editors are being dishonest; it just means that they look for significant effects and give priority to novelty.
Repeated measures analysis of variance (ANOVA) was used to test for significant effects.
For normally distributed data, parametric tests for significant effects were used; for non-normally distributed variables, non-parametric tests were used.
Prior to these analyses, all traits were corrected for significant effects of age, sex, year and ringer (see above).
To test for significant effects of drugs on A and α corresponds to a test for whether γ1j or γ2j is significantly different from zero [33].
For significant effects, discriminant analysis was then performed, with deformation grids used for plastic variables, using Bookstein's [62] thin plate spline algorithm.
To test for significant effects of drugs on fijk corresponds to a test for whether αj is significantly different from zero.
To test for significant effects, we treated each cross-validation fold and each axis as a condition for paired, two-sided sign tests.
The above analysis uses a general linear model to test for significant effects of foundress number and season on the fig-wasp conflict.
To quantify these observations, we performed a 3-Way ANOVA to look for significant effects and interactions between subdivisions and the conditions tested, for the 90/10% probability condition.
