Use the calculator or R-studio to produce a scatter plot. Does there appear to be an association? Compute the value of the correlation coefficient between life expectancy and people per television. Since the association is so strongly negative, one might conclude that simply sending television sets to the countries with lower life expectancies ...

In terms of a correlation coefficient, the size of the observed effect was r = .034. In terms of percentage of variance explained, that is 0.12%. In other contexts this might be considered a trivial effect, but it this context it was so large an effect that the researchers decided it was unethical to continue the study and the contacted all of ...
