Chi-Square Test | Computational Chemistry Resources

Using our fake data, we’ll run a chi-square test. This test is used to evaluate how likely there is to be an observed difference between sets.

Hypotheses

H₀ = in HWE
H_a = not in HWE

> chisq.test(Matrix)

	Pearson's Chi-squared test

data:  Matrix
X-squared = 13.822, df = 2, p-value = 0.0009965

Since the p-value is less than α (0.05 at the 95% level), we reject the (H₀) null hypothesis in favor of the alternative (H_a). There is enough evidence to say that the fake data is not in HWE.
