A programme to calculate the probability of the coefficient of correlation having a certain value by chance. Store x & y data in columns 1 & 2 of statistics aplet & run the programme. The screen will display correlation coefficient R, probability of R arising by chance & relative error of the data to the fitted curve (NOT relative error of R).
