Though the control of variance in resource supply may be a very general and important benefit for groups that share resources there are further benefits of grouping.
Nevertheless, we believed that the control of variance afforded by a within-class block design and the logistical cost advantage of conducting a study in just one school outweighed other potential limitations.
Calculation of the exact prediction error variance covariance matrix is often computationally too demanding, which limits its application in REML algorithms, the calculation of accuracies of estimated breeding values and the control of variance of response to selection.
p < 0.0001 for the comparison of erlotinib-treated vs control (Analysis of Variance to control for the variation among individual mice, N = 12,893 16,140 cells).
In BT16 cells, silencing of NF2, WWC1 and FRMD6using two different siRNAs effectively reduced mRNA expression (d f) and resulted in significantly reduced proliferative activity (MTT assay) as compared with controls (non-target siRNA, g i, means±s.e.m., N=3, ***P<0.001 versus control, **P<0.01, *P<0.05 versus control, analysis of variance (ANOVA) followed by t-test with Bonferroni correction).
Low control coefficient of variance (CV) was 6.7% and high control CV was 4.9%.
The data were subjected to 2 (ROM: low versus high) × 2 (contextual congruency: contextually supported meaning versus contextually unsupported meaning) × 2 (target type: semantic associate versus control) analyses of variance (ANOVAs) with repeated measures, treating either the participants (F 1 ) or the items (F 2 ) as a random effect.
For comparison of the values obtained from the three studied groups (SB ACLR, DB ACLR, and control), analysis of variance (ANOVA) was applied.
Other groups using CGMS have attempted to control sources of variance (24), but even women with normal pregnancies seem to have a wide range of glucose concentrations (Table 1) (26).
One of them (IL-1β6) yielded a significantly improved resolution of CIA (P = 0.0003 as compared with KLH control, analysis of variance); the maximal arthritic score mean was also reduced in the treated group (9.4 ± 1.9 and 14.2 ± 1.7, P < 0.05).
For comparisons between one experimental value and two control values (such as wildtype and unspecific RNAi controls), analysis of variance (ANOVA) was used in addition to confirm the significance values derived from the pairwise t-tests.
