1. In each part, sketch a scatter plot of y vs. x that would plausibly have the listed correlation coefficient. For example, if r = +1, the graph would be a perfect straight line with a positive slope, with all the dots directly on the line. Your sketch doesn't have to be exactly accurate – it just needs to show that you understand the connection between the value of r and the appearance of the graph. a) r = +0.97 b) r = -0.97 c) r = +0.51 d) r = -0.024

Worksheet #5– Correlation
1. In each part, sketch a scatter plot of y vs. x that would plausibly have the listed correlation coefficient.
For example, if r = +1, the graph would be a perfect straight line with a positive slope, with all the dots
directly on the line. Your sketch doesn't have to be exactly accurate – it just needs to show that you
understand the connection between the value of r and the appearance of the graph.
a) r = +0.97
b) r = -0.97
c) r = +0.51
d) r = -0.024
2. Suppose that it was definitively proved that there exists a positive correlation between children playing
more violent video games and committing more violent acts in real life. That is, the more hours a child
spends playing violent video games, the more likely he is to commit a violent act. Would this prove that
violent video games cause children to become more violent? Explain.
