A researcher obtains a Pearson correlation of r = 0.43 for a sample of n = 20 participants. For a two-tailed test, which of the following accurately describes the statistical significance of the correlation?
Added by Lynn A.
Step 1
The degrees of freedom for a Pearson correlation is calculated as \( df = n - 2 \). In this case, with \( n = 20 \), the degrees of freedom would be \( df = 20 - 2 = 18 \). Show more…

A researcher evaluating the significance of a Pearson correlation obtains r = 0.64 for a sample of n = 13 participants. For a two-tailed test, which of the following accurately describes the significance of the correlation? Note: there is a faster way to do this than your book tells you (no need to convert to t) - watch the lecture for more info.

A researcher finds a correlation of -0.43 between an X and a Y variable. Assume alpha = .01 and a one-tailed test. What is the corresponding effect size (r2)?

For a sample of n = 20, how large a correlation is needed to conclude at the .05 level of significance that there is a nonzero Pearson correlation in the population? Assume a two-tailed test. 0.378 0.423 0.360 0.444
