Sentence examples for by a two sample from inspiring English sources

The difference in responses is statistically significant at the 1% level as indicated by a two sample t-test.

The first was the identification of significant differentially expressed genes by comparing FH patients and normal controls in the training set by a two sample t-test.

The nucleocyclic TSSs also showed a significantly asymmetric distribution of each mononucleotide around the TSSs (Fig.  2d), average A/T nucleotide incidences upstream of the TSSs were significantly higher than the incidences downstream (p < 10−116 for A and p < 10−68 for T by a two sample z-test described in Methods).

The ratios were compared in each case by a two sample t-test of log abundance ratios to the pool; proteins identified in all triplicate samples for the respective comparison and having a t-test p-value < 0.05 and a fold change > 1.2 or < 0.83 were regarded as being differentially expressed across the time course.

The significance of comparison among diversity indexes were accessed by a two sample z-test for comparison between means [ 78]. fru C3 exon and I3 intron haplotype networks were inferred by TCS v 1.21 software [ 79] using statistical parsimony with a 95% connection significance [ 80], and was manually converted to Newick tree format for some of the neutrality tests.

We tested whether consultation to mail out intervals were associated with response to questionnaires by using a two sample t test.

The genes in the final dataset were ordered by p-value in a two sample equal variance t-test.

This work suggests that, on an individual basis, blood-Hg levels from separate exposure time periods do not provide a reliable estimate of longer term exposure as represented by a three sample average.

P-values were calculated by conducting a one sample t-test on the adjusted intensity data of the entire array of selected hybridizations at each time point.

T-tests (calculated by conducting a one sample t-test on the adjusted intensity data of the entire array of selected hybridizations at each time point) were performed between samples to assess reproducibility and similarity.

We calculated all pair-wise comparisons of allele sharing between two cases and all pair-wise allele sharing between two controls and tested the difference of the means of the two distributions by a Welch Two Sample t-test.
