How can two continuous variables be compared and contrasted with each other. Give at least one example of each of the following: charts, summary statistics and regression models.

Draw a scatter plot of x and y (assume each sample has n=10 and ranges broadly between 0 and 1) in which the true correlation coefficient is -0.95. Then draw another chart that would be indicative if the true correlation between x and y was approximately 0.5. Label each chart clearly.
