How do I find out how many people have a score above a certain value?

Percentiles give the percentage of people who have a score below a threshold score.

Percentile (score) = 100$$\frac{\mbox{n} \leq \mbox{score}}{\mbox{N}}$$

1 - Percentile (score) = 100$$\frac{\mbox{n} \gt \mbox{score}}{N}$$

The percentiles for each score are routinely outputted using the frequency procedure in SPSS.
