Suggested answer to exercise: Eye colour and sex, 2

Question 2: What methods could we use to test the null hypothesis that observed eye colour in not related to sex?

Suggested answer

Eye colour and sex and both qualitative, categorical, or nominal variables.

We could use either the chi-squared test for a contingency table or Fisher's exact test.

The eye colour categories are not ordered, so we would not use the chi-squared test for trend.
