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 ...

1. The Pearson Correlation Coefficient. Correlation. In statistics, the word "correlation" has a very specific meaning. Statistical correlation means that, given two variables X and Y measured for each case in a sample, variation in X corresponds (or does not correspond) to variation in Y, and vice versa.

3. No Correlation:The points on the graph would not represent a line at all. (r = 0 ) Correlation Coefficient (r) - Used to measure how well the data matches a line that would best fit the data.-The correlation coefficient will be a number between -1 and 1. **The closer the number is to 1 or -1, the better the data matches the line of best fit.
