Question
1. If r= -0.333, we can say thata. there is no correlation b. a perfect direct correlation c.a low reverse correlation d. a perfect inverse correlation.
2. An investigation wants to know if the use of contraceptives is related or not to the fact of being married or being single, if the calculation of correlation index obtained was 0.39, the conclusion is a. the correlation is considerable, marital status influences the use of contraceptives. b.the correlation is low, so the marital status has some influence on the use of contraceptives c. the correlation is low, so the correlation has little influence on the use of contraceptives d. there is no correlation, the marital status does not influence the use of contraceptives. 1.

Explanation / Answer
1.If r=-0.333, we can say that
c. a low reverse correlation...becouse the value of r is negative and it is much lower than 1
2. An investigation wants to know if the use of contraceptive is related or not to the fact of being married or being single, if the calculation of correlation index obtained was 0.39 ,the conclusion is
b.the correlation is low ,so the marital status has some influence on the use of contraceptives
