The correlation coefficient computed for two parameters measured in 429 patients is r = 0.829. This means that:   a. The two parameters are inversely correlated, and the  association is strong, r is negative and close to 1   b. There are too few cases (under 500) and we do not trust this coefficient’s value   c. The two parameters are directly correlated, and the association is strong, r is positive and close to 1   d. The two parameters are directly correlated, and the  association is weak, r is positive and close to 0
