Calculating Correlation (Pearson's r)

How to calculate Pearson's r correlation coefficient
Warning: I calculated the degrees of freedom (df) incorrectly.
The N is 7, not 14.
I counted the number of scores (which is typical in other calculations), instead of the number of cases. In this example, the df is indeed 5, meaning the critical value is 0.669, which is greater than the calculated r of 0.62, meaning we accept the null = no correlation.
