The expected urine output for an adult is 0.5ml/kg/hr. This roughly equates to 30-40ml per hour in an average sized adult.
Interpreting Norm-Referenced Scores Percentile Ranks Percentile ranks, which range from 1 to 99, are commonly used for reporting test results to students and their parents/guardians. You may interpret a percentile as the percentage of students in a norm group whose scores fall below a given student's scale score.
Finally, consider the 50th percentile of the numbers 2, 3, 5, 9, 11. R = 50/100 x (5 + 1) = 3. IR = 3 and FR = 0. Whenever FR = 0, you simply find the number with rank IR. In this case, the third number is equal to 5, so the 50th percentile is 5. You will also get the right answer if you apply the general formula: 50th percentile = (0.00) (9 - 5) + 5 = 5.
