Percentile (first test - unselected sample)

The percentile for the current Total Error Score with respect to a distribution of Total Error Scores obtained from an 'unselected' group of subjects aged 15 to 45 for their first attempt at the test.

For example, a figure of 90% means that the current Total Error Score would be in the top 10% for subjects with no previous experience of color matching.

The analysis is based on results for 494 'unselected' subjects.
