Question
Calculate SP (the sum of products of deviations) for the
following scores. Note: Both means are decimal values,
so the computational formula works well.
X Y
0 2
0 1
1 0
2 1
1 2
0 3
Assume a two-tailed test with .05.
(Note: The table does not list all the possible df values. Use the sample size corresponding to the appropriate df value that is listed in the table.)
a. A correlation of r 0.30.
b. A correlation of r 0.25.
c. A correlation of r 0.20.
