Answer:
between -1 and +1
Step-by-step explanation:
The possible range for a correlation coefficient is between -1 and +1. Correlation coefficient is a statistical measure of the relationship between of two variables. The values of correlation coefficient range between -1.0 and 1.0. The value ±1 indicates the strongest possible agreement and 0 the strongest possible disagreement. Any correlation coefficient greater than 1.0 or less than -1.0 means that there was an error in the correlation measurement.
