Answer: D
The coefficient of correlation ranges from -1.00 to 1.00.
A value of +1 means a perfect positive relationship, -1 a perfect negative (inverse) relationship, and 0 no linear relationship. Every value of the Pearson coefficient lies between these limits.
The ranges 0 to 1 and 1 to 0 leave out negative correlations, and -1 to 0 leaves out positive ones, so each covers only half of the possible values.
