If both height and weight are normally distributed, we use the Pearson’s correlation; otherwise Spearman’s correlation coefficient will be presented. Spearman’s correlation is also applicable for two categorical ordinal variables like pain intensity (no, mild, moderate, severe) with burn-surface-area (< 10%, 10% 19%, 20% 29%, ≥ 30%). Table I shows the correlation coefficient between height and ...

Self-report correlational data support self-determination theory's (SDT's) postulate that there are three basic psychological needs, for autonomy, competence, and relatedness, which combine additively to predict well-being and thriving. However, experimental research in the SDT tradition has focused only on autonomy support, not relatedness and competence support. To fill this gap, we employed ...

OBJECTIVES To provide normative data for the Hospital Anxiety Depression Scale (HADS). DESIGN Repeated measures and correlational. METHODS The HADS was administered to a non-clinical sample, broadly representative of the general adult UK population (N = 1792) in terms of the distributions of age, gender and occupational status. Correlational analysis was used to determine the influence of d...

AIM To investigate factors affecting women's intention to smoke during pregnancy. DESIGN A descriptive, correlational, cross-sectional study, employing the Theory of Planned Behaviour (TPB). METHODS A questionnaire that was constructed based on a literature review of research on smoking during pregnancy and on the TPB was administered to 201 Israeli female smokers aged 19-46. Descriptive, c...

When a trait's effect on fitness depends on its interaction with other traits, the resultant selection is correlational and may lead to the integration of functionally related traits. In relation to sexual selection, when an ornamental trait interacts with phenotypic quality to determine mating success, correlational sexual selection should generate genetic correlations between the ornament and...

OBJECTIVE We evaluate and quantify the effects of human, robot, and environmental factors on perceived trust in human-robot interaction (HRI). BACKGROUND To date, reviews of trust in HRI have been qualitative or descriptive. Our quantitative review provides a fundamental empirical foundation to advance both theory and practice. METHOD Meta-analytic methods were applied to the available lite...
