In another case transfer data of positivity trials could not been reliably obtained at time 1 because of problems with artefacts, and the group mean was entered into the analysis instead.
These mean values were entered into a 2×2×3 [group (older and younger)×planar orientation (upright and inverted)×angular disparity between target and choice face (0°, 45°, 90°)] repeated measures analysis of variance (ANOVA).
Mean mood ratings were entered into a 2×2×2 repeated measures ANOVA with mood dimension of the selected music (positive/negative), arousal dimension (high/low) and time (before/after the music).
Demographic variables such as sex and race of the child, maternal education, and household income, as well as mean serum cotinine were entered as fixed effects, while child age, and creatinine or creatinine z-scores were entered as time-varying effects.
The remaining mean correct probe RTs were entered into a 2 (probe location age: infant, adult) ×2 (probe location race: South Asian, White) ×2 (participant race: South Asian, White) analysis of variance (ANOVA).
All continuous predictor variables were mean centered before they were entered into the multivariable regression models.
Sampling order (expressed as days since first day of sampling) and the five water parameters (NO3 N, temperature, conductivity, dissolved oxygen, pH), expressed as a mean for each spring, were entered as independent variables.
Item means across all 6 appraisers were entered into the analysis.
All dependent variables were entered as means per experimental container, and their values were log-transformed if necessary to meet the assumptions of normality in data and residual distributions.
