Examples of positive and negative correlations

Examples Of Positive And Negative Correlations. For example sleeping is negatively correlated with sleepiness such that an increase in one corresponds to a decrease in the other and vice versa.

A line approximating a positive correlation has positive gradient and a line approximating negative correlation has a negative. Positive Correlation vs Negative Correlation.

In both the extreme cases there is either perfect negative or perfect positive correlation respectively. However No cause and effect is implied.
