The correlation coefficient, or r, always falls between -1 and 1 and assesses the linear relationship between two sets of data points such as x and y. You can calculate the correlation coefficient by dividing the sample corrected sum, or S, of squares fo
and Prism will subtract 1 from whatever you enter as n to calculate the df value it uses in ANOVA. If you enter df+1 as n, then when Prism subtracts 1, the correct df value will be used in the calculation. For linear regression, ...
