Potential mean level differences between the measurements were determined by means of a one-way repeated measures ANOVA with LSD comparisons of the means.
In addition, gender differences usually have more impact in terms of mean level differences and not on the factor structure (e.g. Martin 2007).
Further, no results were moderated by participant race or ethnicity, and there were no significant mean level differences across race and ethnicity for any of the main study variables.
The longitudinal design not only allows for an examination of the between person effects that look at mean level differences, but more importantly, it allows for the examination of within person effects (which cannot be captured in cross-sectional designs) of the dynamic changes in depression and PTSD within an individual woman over time that can contribute to episodes of alcohol use.
The present study examined (1) mean-level differences in self-esteem and Big Five personality traits between individuals with and without diabetes; and (2) demographic, clinical, and psychological correlates of patients' self-esteem and Big Five.
In a meta-analysis comparing studies that used computerized and paper-and-pencil questionnaires, as well as face-to-face interviews, Richman et al., (1999; see also Bauer et al., 2004; Holbrook, Green, & Krosnick, 2003; Marshall, De Fruyt, Rolland, & Bagby, 2005) reported mean-level differences in personality measures related to social desirability.
Figure 1 shows the mean expression level differences of known genes, which gave a signal in at least two experiments in one group.
For this purpose, we calculated the log ratio between human-orangutan and chimpanzee-orangutan squared mean expression level differences for each probe set.
Women within the highest BMI quintile on average had a substantially lower mean total hCG level compared to women within the first quintile (average difference 9369 ± 729 IU/L, P < 0.001; Supplemental Table 4) and mean total hCG level differences according to parity and child gender ranged between approximately 2000 4000 IU/L.
Table 4 Mean plot-level difference (d) in standing dead biomass (oven-dry kg) by tree component and estimation method (1 = CRM vs. CRM+DRF and 2 = CRM vs. CRM+DRF+SLA) for quaking aspen in the Lake States (2005-2009) anDouglas-firin in the Pacific Northwest (2001-2009).
