Make up an example of two variables that might be related in such a way that the Pearson correlation coefficient could not be used to measure the relationship strength but the Spearman coefficient could be used instead. Explain the rationale for your answer.

2. Use an example to describe a situation where a scatter plot of the data would result in all of the data points falling exactly on a straight line. What would be the calculated value of r?
