11th point) and recalculate. How does the removal of that point effect correlation for each?

Look at the above attached datasets. Calculate the correlation coefficients for each and tell whether there is a reasonable correlation or not. Now remove the last point of each (the 11th point) and recalculate. How does the removal of that point effect correlation for each? Explain the results for each and why it happens. Need 75 to 100 words on this.
