A researcher calculates a correlation of .49 for a sample of 18 people. Assuming H₁ is non-directional, which of the following is the correct way to present this analysis? A) r(16) = .49, p .05 B) r(17) = .49, p .01 C) r(18) = .49, p

Question

A researcher calculates a correlation of .49 for a sample of 18 people. Assuming H₁ is non-directional, which of the following is the correct way to present this analysis? A) r(16) = .49, p > .05 B) r(17) = .49, p > .01 C) r(18) = .49, p < .01 D) r(16) = .49, p < .05

Quizplus · Accepted Answer

The correct way to present this analysis is "r(16) = .49, p < .05." The degrees of freedom (df) for a correlation is calculated as n - 2, where n is the sample size. Here, n = 18, so df = 18 - 2 = 16. The p-value indicates the significance of the correlation, and "p < .05" suggests that the correlation is statistically significant.
