Quizplus · Accepted Answer

Correlation coefficients range from -1 to +1, with values closer to -1 or +1 indicating a stronger relationship between variables. A correlation of +.89 and -.89 are both strong and equally so, as they are both very close to the maximum value of +1 and minimum value of -1. It is important to note that correlation coefficients do not indicate cause and effect, as correlation does not necessarily imply causation. A correlation of +1.5 is not possible, as the range of correlation coefficients is limited to -1 to +1.
