The correlation coefficient measures the strength and direction of the relationship between two variables. In this case, the correlation coefficient between levels of stress and measures of physical and psychological well-being would indicate the extent to which stress can predict well-being. This would be more useful than measures of central tendency, such as mean or median, which only provide information about the distribution of scores, or the standard deviation, which indicates the variability of scores around the mean. The ANOVA technique would not be appropriate in this context as it is used to compare means between multiple groups, whereas stress and well-being are continuous variables.
