What is hypothesis testing?

Statistical test to assess if something is true from data

Initial assumption when testing for correlation

Assume no correlation

What does ρ\rho (rho) represent?

Population correlation coefficient

What does H0H_0 state in correlation tests?

ρ=0\rho = 0 (no correlation)

What does H1:ρ>0H_1: \rho > 0 test for?

Positive correlation

What does H1:ρ≠0H_1: \rho \neq 0 indicate?

Two-tailed test

5% significance level means what % certainty?

95% certainty

What are critical values?

Cut-off points from tables for different significance levels

When to reject H0H_0 in correlation test?

When observed rr exceeds critical value in direction tested

Spearman's rank: association or correlation?

Association (not ρ\rho)
