Distinguish between positive and negative correlations. Suggest one pair of health-related variables that is probably positively correlated, and one that is probably negatively correlated. For each pair, draw a hypothetical scatterplot, being sure to label the axes.
What will be an ideal response?
In a positive correlation, scores on one variable go up or down as scores on the other do. In a negative correlation, scores on one variable go down as scores on the other go up. Number of cigarettes smoked per day and sick days taken might be positively correlated. By contrast, scores on a measure of social support might be negatively correlated with number of physical symptoms of ill health reported.
