You can put this solution on YOUR website!
Go to
http://www.graphpad.com/quickcalcs/linear1/,
input the year values in the X column and the L values in the Y column.
View the results, and look at the "Goodness of Fit" results.
The R square value would be 0.9538. The square-root of this is 0.9766 to four significant places.
This would be the correlation coefficient for the regression line.
