There's another program %TILE in the EXAMPLES that can be used with data in a list:
Code:
« SWAP SORT DUP SIZE 1 + ROT 100 / * → p   « DUP p FLOOR GET SWAP p CEIL GET + 2 /   » »
• Q1: « 25 %TILE »
• Q2: « 50 %TILE »
• Q3: « 75 %TILE »

Examples:

Taken from Quartile.

{ 6 7 15 36 39 40 41 42 43 47 49 }
• Q1: 15
• Q2: 40
• Q3: 43

{ 7 15 36 39 40 41 }
• Q1: 11
• Q2: 37.5
• Q3: 40.5

But this might not be exactly what you expect.

Kind regards
Thomas
