2. Association and Correlation: Correlation
Strength of a Linear Relationship: Pearson Correlation Coefficient
For two variables #X# and #Y# the following sample statistics are known:
- Sample standard deviation of #X#: #s_X = 9.59#
- Sample standard deviation of #Y#: #s_Y = 9.14#
- Sample covariance: #s_{X,Y}=-65.389#
Calculate the Pearson Correlation Coefficient between #X# and #Y#. Round your answer to #3# decimal places.
| #r_{X,Y}=# |
