Sentence examples for underestimated sample from inspiring English sources

Whereas an underestimated sample size may produce an underpowered study, an overestimated sample size raises ethical issues.

An underestimated sample size or less sensitivity of used questionnaires has to be considered as possible reasons for lacking significance.

We calculated our sample size based on prevalence of 20% reported by the two previous studies [ 22, 23], which might had resulted in underestimated sample size.

Mean bias based on the Bland-Altman plots was 9.9 g/L (95% limits of agreement, -3.1-23.0) indicatheg that the refractometer underestimated sample colostral IgG concentrations by 9.9 g/L, on average.

Mean bias based on the Bland-Altman plots was 11.3 g/L (95% limits of agreement, -0.2-22.8) indicatheg that the refractometer underestimated sample serum IgG concentrations by 11.3 g/L, on average.

Let w i denotes the Welch t-statistic for gene i; w i can be written as In the case where the Welch t-statistic is used, since thousands of genes are evaluated simultaneously, when some of them have underestimated sample variance under two conditions by chance, their absolute test statistic becomes large even though their mean difference is not meaningfully large.

The first method, loss on ignition (LoI), underestimates sample C stocks by 4.9 ± 0.8% compared to results from the elemental analysis across all samples.

Genetic selection may therefore have affected detected prevalences; a selection of genotypes at risk for CS in both AS and CS positive flocks might have overestimated the sample population prevalence of CS and underestimated this sample population prevalence of AS.

Simulation studies have shown that the sampling error of genetic correlations may be seriously underestimated for sample sizes under 100, especially if the corresponding heritabilities of the traits are low or genetic correlations are high [45], [46].

During life the trabecular tissue was intermixed with soft tissue - bone marrow, blood vessel, nervous tissue and fat - and if the Hg concentrations in the soft tissues were more or less similar to that of the compact bone tissue, then we underestimated the sample weight in our calculations.
