Abstract
The confidence intervals on the multiple correlation coefficient were computed by using directly Fisher's formula (1928) for several sets of variables including both cases of even and odd numbers for each of the valuesN(sample size)=15, 20, 30, 40, 50, 75, 100 and 200. These figures can be used not only to estimate the 90 percent confidence interval but to test hypothesis H0: ρ=ρ0, where ρ0 is not necessarily zero.
