Question

When computing a correlation coefficient, if you have 27 degrees of freedom, your sample size must be _______.

Enter your answer as a whole number with no decimal places (i.e., 10, not 10.1, not 10.01).

Definition Definition Statistical measure used to assess the strength and direction of relationships between two variables. Correlation coefficients range between -1 and 1. A coefficient value of 0 indicates that there is no relationship between the variables, whereas a -1 or 1 indicates that there is a perfect negative or positive correlation.
