All answers were accepted on appeal for this question about the population distribution of intraocular pressure. In practice the distribution is approximately Gaussian with a mean near 15-16 mmHg and a standard deviation of about 3 mmHg, but it is not truly normal: it is skewed towards the higher pressures, which is why a cut-off of 21 mmHg (mean plus two standard deviations) excludes rather more than 2.5% of people, and mean pressure also differs between ethnic groups.
