Correlational studies aim to measure the strength and direction of the relationship between two variables. The numerical value obtained for the correlation coefficient describes the consistency of this relationship, with values ranging from -1 to +1. A correlation coefficient of -1 represents a perfect negative relationship, 0 represents no relationship, and +1 represents a perfect positive relationship. Therefore, the best choice for the numerical value that describes consistency in a correlational study is the correlational coefficient.
