2. Find an article on correlation and answer the following questions:
What are the two variables being studied?
Did the article include a scatterplot?
Does the association appear to be linear or curved?
Would you say that the correlation is weak or strong?
Was the correlation coefficient included?
Could you make a prediction based on the data?

3.       In this week’s reading from chapter 10, linear correlation, we compare two different variables to look for a positive, negative, or possibly no correlation.  What two variables might you want to compare?  What data can you find on the Internet about these two variables? Please include the website in which you found your data.

4.   If the scatterplot of two variables yields points that make a perfect straight line (either positive or negative), they are said to have “perfect linear correlation”- the correlation coefficient is either r = 1, or r = -1.  Can you think of two variables that have perfect linear correlation?  Can you think of two variables that have absolutely no linear correlation at all- a linear correlation r = 0?
