With regard to correlational research,which of the following is true?

A) Correlational evidence provides stronger evidence about cause and effect than does quasi-experimental evidence.
B) A correlation coefficient of −.32 reflects a stronger degree of relation than a correlation coefficient of +.30.
C) Correlational studies involve independent samples.
D) all of these

Correlation coefficients range from -1 to +1, with a coefficient close to -1 or +1 indicating a strong relationship and a coefficient close to 0 indicating a weak or no relationship. Therefore, a correlation coefficient of -0.32 indicates a weaker degree of relationship than a correlation coefficient of +0.30. The other options are incorrect because correlational evidence does not provide strong evidence about cause and effect, and correlational studies do not involve independent samples.
