Percentile analysis preferences

Use this view to customize the percentiles that are reported in the Page Percentile report or to customize the requirements on a percentile response. The defaults, 85, 90, and 95, are sufficient for most purposes. However, if you need to report on a different percentile set, or to set a different percentile requirement, you can edit the percentiles or add new percentiles.
Open the Percentile Analysis Targets preference page. Click Window > Preferences > Test > Percentile Analysis Targets.
