Run your correlation analysis. Your cells should include your
deviations, squared deviations (including, SSx and SSy), products
(including SP), computed r coefficient, computed t-value, degrees
of freedom, and critical t-value.
Grading Rubric:
1 point: Deviations accurate
2 point: Squared deviations accurate
1 point: Products accurate
1 point: r coefficient accurate
0.5 point: computed t-value accurate
0.5 point: critical t-value accurate

1. For a pair of sample x- and y-values, what is the difference
between the observed value of y and the predicted value of y? a) An
outlier b) The explanatory variable c) A residual d) The response
variable
2. Which of the following statements is false:
a) The correlation coefficient is unitless. b) A correlation
coefficient of 0.62 suggests a stronger correlation than a
correlation coefficient of -0.82. c) The correlation coefficient,
r, is always between -1 and 1....
