2 For a sample of n = 20 individuals, how large a Pearson correlation is necessary to be statistically significant for a two-tailed test with = .05?
3 The Pearson correlation is calculated for a sample of n = 25 individuals. What value of df should be used to determine whether or not the correlation is significant?

X Y
1 5
3 3
8 1
5 A set of n = 5 pairs of X and Y values has SSX = 4, SSY = 16 and SP = 8. For these data, what is the Pearson correlation?
Which of the following sets of correlations correctly shows the highest to lowest degree of relationship?
