# PERCENTILE

The PERCENTILE( ) function returns the specified percentile out of some set of values. This could be useful for establishing a threshold of acceptance, such as for candidates who score above the 90th percentile on a certification exam, or rewarding sales reps in the top percentile with regard to deals won in the past year.

• PERCENTILE(numeric, k)
• where numeric is a fact or metric
• where k is a value between 0 and 1 representing the percentile you want returned specified as a decimal. k accepts constants as inputs. Numeric values must be expressed in the following format: 0.xx
• For metric expressions, you should compute percentiles using syntax similar to the following: `SELECT PERCENTILE((SELECT SUM([fact]) BY [attribute]),0.25)`
• PERCENTILE(numeric, k%)
• where numeric is a fact or metric
• where k% is a number between 0 and 100 representing the percentile you want returned. k accepts constants as inputs, followed by percent signs as inputs.
• For metric expressions, you should compute percentiles using syntax similar to the following: `SELECT PERCENTILE((SELECT SUM([fact]) BY [attribute]),25%)`

Syntax

`SELECT PERCENTILE(…) [ASC|DESC] [BY(…)]`
` SELECT PERCENTILE(metric, decimal)`
` SELECT PERCENTILE(metric, percentage)`
` SELECT PERCENTILE(fact, decimal)`
` SELECT PERCENTILE(fact, percentage)`
` SELECT PERCENTILE((SELECT SUM([metric]) BY [attribute]), decimal)`
` SELECT PERCENTILE((SELECT SUM([metric]) BY [attribute]), percentage)`

Examples

`SELECT PERCENTILE(Amount, 0.75)`
` SELECT PERCENTILE(Amount, 75%)`
