Question

Using a two-tailed test with ⍺ = .05, how large of a correlation would be needed to be
statistically significant for each of the following samples?
a. A sample of n = 10
b. A sample of n = 20
c. A sample of n = 30

Definition Definition Relationship between two independent variables. A correlation tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
