You can use the new suite of analytic functions introduced in SQL Server 2012: SELECT DISTINCT [Month], Mean = AVG (Score) OVER (PARTITION BY [Month]), StdDev = STDEV (Score) OVER (PARTITION BY [Month]), P90 = PERCENTILE_CONT (0.9) WITHIN GROUP (ORDER BY Score) OVER (PARTITION BY [Month]) FROM my_table.

Percentiles divide ordered data into hundredths. To score in the 90th percentile of an exam does not mean, necessarily, that you received 90% on a test.

For the test theory, the percentile rank of a raw score is interpreted as the percentage of examinees in the norm group who scored below the score of interest.. Percentile ranks are not on an equal-interval scale; that is, the difference between any two scores is not the same between any other two Returns the k-th percentile of values in a range. You can use this function to establish a threshold of acceptance. For example, you can decide to examine candidates who score above the 90th percentile. If k is non-numeric, PERCENTILE returns the #VALUE!

Thus 90 percentile values can be extremely useful in the result analysis phase of the test cycle. Scenario 2: To understand the spread of response time values. Taking a difference of the 90 percentile value and the average response time value and dividing this difference with the average response time value gives an idea of the spread of different data points.
