We initially attempted to measure growth in terms of mass in liquid medium, but switched to measuring radial growth because of large variation between replicates.
Animal studies are often regarded with scepticism because of large variation in study design and outcome measures.
39 62 Probably in part because of large variation in the definition, the prevalence of working long hours also varied substantially, ranging from 4.1% to 69.8%.
However, because of large variation in criteria used in the articles for defining disease, or disease progression, pooling of the data generally was not possible.
Although a simple comparison is not accurate because of large variation between the surveys, the difference could be explained as follows.
However, today, face recognition remains challenging because of large variations in facial image appearance due to multiple factors including facial feature variations among different subjects, viewpoints, lighting conditions, and facial expressions.
However, the h-index may not fairly compare researchers from different fields of research, because of large variations in publication type and frequency and citation volumes between fields.
Until now that basic finding had not been replicated, likely because of large variations in the cognitive measures and connectivity methods employed across studies.
Because of large variations in their design (type of patients, observed mortality (33 to 60%), mix of H- and Ĉ-statistics), it is difficult to perform meaningful comparisons between them.
The new understanding of As metabolism creates interesting challenges in evaluating health effects of in populations exposed to iAs because of large variations in the factors that affect metabolism, such as nutrition (Gamble et al. 2005), genetics (Chung et al. 2002), sex (Shraim et al. 2003; Tseng et al. 2005), and age (Chowdhury 2003; Tseng et al. 2005).
When the distribution of selection gradients is uniform, genetic correlations have no effect on the mean rate of adaptation, because high rates in directions of large variation are offset by low rates in directions of small variation (Hansen and Houle 2008; Kirkpatrick 2009).
