The significance test for a Pearson correlation coefficient is not robust to violations of the independence assumption. If this assumption is violated, the correlation significance test should not be computed. SPSS© computes the Pearson correlation coefficient, an index of effect size. The index ranges in value from -1.00 to +1.00.

Pearson correlation of X and Y = 0.949. P-Value = 0.000. Note the Pearson’s correlation between x and y is 0.949. The P-value=0.000 is for testing (the true correlation is zero. It means there is no linear relationship between x and y) versus (the true correlation is not zero. It means there is a linear relationship between x and y).

While focused on the p value, hit F9 50 times, and count the number of instances p < .05 (see class notes to help understand what this means). Remember, any significant relationship found is due to chance. While focused on the correlation (r), hit F9 50 times, and count the number of instances that the magnitude of r is greater than 0.3.
