There is no such thing as 100th percentile. The person with the highest score is higher than everybody else but not higher than himself or herself. So the maximum possible is 99.99 percentile or so. Which can be regarded as 100th percentile by many.
Is there such thing as 100 percentile?
In fact, for this very reason, there’s no such thing as a 100th percentile. The person with the highest score is higher than everybody else, but not higher than herself, so she’s in the 99th percentile. If we are sticking with whole numbers, the 99th percentile is the highest possible percentile.
Why 100 percentile is not possible?
To put it in words, being in the 100 percentile would mean that 100% of the group has marks below yours. But since 100% of the group would include you, and your mark could never be below your mark, then 100% of the group could not be below you. Therefore you could never be in the 100 percentile.
Are there 99 or 100 percentiles?
Most quantiles of this distribution exist and are unique, but the median (50th percentile) is inherently ambiguous. In R, they go half-way: quantile(c(runif(100), runif(100) + 2), 0.5) returns about 1.5. Example of 3): For a normal distribution, the 100th and 0th percentiles do not exist (or they “are” ±∞).
Is the 99th percentile the highest?
