The compounds 8Q and 8J had significantly smaller variations in their LD50 ranges across the 36 screened tumor cell lines presumably due to their cross-reactivity with most antiapoptotic Bcl-2 subfamily members.
A formal test of this observation revealed that variation in adult foot morphology was significantly smaller than variation in juvenile foot morphology, implying that a common adult phenotype exists among species, despite large differences in their developmental trajectories.
These results indicate that variations within species are significantly smaller than variations among species.
Note that intraspecific variation was significantly smaller than interspecific variation, as described below.
Importantly, even in the presence of drugs, reproducibility between replicates (12 per treatment for each treatment and cell line) remained very high and sample to sample variation within each group was significantly smaller than any variation arising from treatment or genetic variability.
Previous studies found that the variation between doctors within hospitals was significantly smaller than the variation between hospitals, which we found to be small itself, or even insignificant [ 21, 38].
These numerical investigations show that the proposed model appears as a very good predictor of shear strength and has a significantly smaller coefficient of variation compared to the other models.
Therefore, the within-hospital variation should be significantly smaller than the between-hospital variation.
However, the range of variation among Moroccan accessions for flowering time (49 200 days) and leaf number (40 150 leaves) was significantly smaller than the Iberian variation (23 200 days and 7 150 leaves).
Building upon this previous work, [9], Kerr et al. (2007) [16], working with a larger number of species and samples, found significantly smaller amounts of interspecific variation between closely related allopatric bird taxa (that often are known to hybridise), potentially compromising the universal applicability of cox1 DNA barcoding.
