Homework SourseA set of n 5 pairs of X and Y values has SSX 16 SSY 4 and
A set of n = 5 pairs of X and Y values has SSX = 16, SSY = 4 and SP = 2. For these data, the Pearson correlation is ____.
r = 2/64
r = 2/8
r = 8/8
r = 64/8
| r = 2/64 | ||
| r = 2/8 | ||
| r = 8/8 | ||
| r = 64/8 |
Solution
r = SP/sqrt SSX*SSY
r = 2/sqrt(16*4)
r = 2/sqrt 64
r = 2/8
answer: r = 2/8
