Question

Quizplus · Accepted Answer

A correlation coefficient of 1 indicates a perfect positive correlation, meaning that the two variables are completely correlated. A correlation coefficient of 0 indicates no correlation, and negative correlation coefficients indicate a negative correlation. 10 and 100 are not possible correlation coefficients as they are not within the range of -1 to 1. Nonexistent is not a valid answer as there must be some level of correlation between two variables that are being analyzed.
