- R is the correlation coefficient for the plot of dissolved oxygen versus Julian day for the interval J,D, UR) to 2tK), A perfect correlation would have 

 R equal to 1.0 and a probability (P) of that the correlation occurred by chance The columns "R for P<0.05" give the correlation coefficient necessary 

 to statistically state that the correlation occurred by chance is <().05.
