Scatter plot and correlation:
1) Cause of Global Warming If we find that there is a linear correlation between the concentration of carbon dioxide (Co2) in our atmosphere and the global temperature; does that indicate that changes in the concentration of carbon dioxide cause changes in the global temperature? Why or why not?
2) a. Construct a scatter plot.
b. Find the value of the linear correlation coefficient r, and then determine whether there is sufficient evidence to support the claim of a linear correlation between the two variables.
c. Identify the feature of the date that would be missed if part (b) was completed without constructing the scatter plot.
