Based on these results, we conducted statistical tests on mean amplitudes in the epoch from 50 to 90 ms after stimulus onset (dashed lines in Figure 3A).
Most of our tests on mean length of stay and the proportion of day case activity in total elective admissions are consistent with a reduction in unit costs associated with introduction of the tariff.
IQR - Inter-quartile range, SE-Standard error, Ŧ Test statistic - χ2 test or t-test on means Fifteen percent (145/954) of the 2002-2006 cohort developed hypoglycaemia (< = 3 mmols/l) post admission as did 15% (42/283) of the 2006-2009 cORort OR = 0.97, 95% confidence interval [0.67-1.41]; P = 0.88.
In meta-analysis often performed to draw standardized information about effect sizes from heterogeneous data sets, the effect sizes are being quantified by calculating Cohen's d [15] as a widely used standardized effect size measure appropriate to use in the context of a t-test on means.
Using JMP, we performed statistical analyses (χ, Van de Waerden's, Wald's and Student's t-tests) on means and distributions to test various hypotheses (see below).
Synonymous substitution rates of putative orthologs between barley and rice within AD's differed significantly from all distributions that were obtained for the different types of rice duplications (pair wise test on means, Tukey HSD, p < 0.05).
When a population growth rate of 1 × 10−3, and mutation rate heterogeneity described by a gamma distribution with α equal to 0.2, were incorporated into simulations, detection rates were significantly lower (P < 8.18 × 10−3, paired Student's t-test on means for all tests at each value of ρ, see Figure 2).
A t-test on mean values confirms that these differences are statistically significant at the 1% level.
T-tests on mean correlation coefficients, weighted for sample size [31], demonstrated that only two relationships (hemagglutination and hemolysis, anti-E.
At the end of both experiments, but not at the start, community differences between the P and Control treatments were significantly larger than between the N and Control treatments (t-test on mean Sørensen distances between treatments p<0.05).
Moreover, the random rotation group generally moved faster, and movement durations were accordingly reduced in this group (p < 0.001, Wilcoxon rank-sum test on mean duration).
