# Test of Independence: 5df

* Large Effect Size*

Power analysis for a test of independence with five degrees of freedom was conducted in G-POWER using an alpha of 0.05, a power of 0.80, and a large effect size (*w* = 0.5) (Faul et al., 2013). Based on the aforementioned assumptions, the desired sample size is 52.

**Medium Effect Size**

Power analysis for a test of independence with five degrees of freedom was conducted in G-POWER using an alpha of 0.05, a power of 0.80, and a medium effect size (*w* = 0.3) (Faul et al., 2013). Based on the aforementioned assumptions, the desired sample size is 143.

**Small Effect Size**

Power analysis for a test of independence with five degrees of freedom was conducted in G-POWER using an alpha of 0.05, a power of 0.80, and a small effect size (*w* = 0.1) (Faul et al., 2013). Based on the aforementioned assumptions, the desired sample size is 1293.
