A single jury is still too small of a sample size to be statistically significant. If you have more than two groups in the population (races in this case) then you need at least 5 <i>expected cases</i> of each in order for analysis of the actual versus expected proportions to be meaningful, which you can&#x27;t get with 12 jurors. The closest you can get to it is if there are 3 groups evenly divided in the population, which gives you 4 expected cases each. If you had only 2 groups in the population that were each 50% then you would have 6 expected cases each. However, when analyzing sample proportions of 2 groups you need at least 10 cases each.<p>Those minimum case numbers are needed in order for the central limit theorem to be applicable in the statistical analysis.
