Look at the attached scatterplot below that compares Per Capita Meat Consumption and Colon Cancer incidence per country. Now that you are equipped with the concept of correlation, do you think that we can make a statistically significant inference about the relationship between meat consumption and colon cancer?
Consider the following points in answering this question:
Do we need to survey more countries to make a conclusion?
How strong is the correlation? What do you think the r^2 would be if you ran a linear regression?
Are there any other factors we should take into consideration besides meat consumption?
