Percentiles and distributions

Prozach

Completely new to rapidminer.

I have gone through the tutorials but have not found exactly what I am looking for.

What I have so far:  I am able to connect to a MySQL database and pull the data I want to analyze.
Most of the crunching has already been done and I just want to figure out the percentiles or distribution of the sample set.

I can't quite figure that out in the context of Rapid Miner.

My data consists of two values.  A possource and a HUNC.
The possource is one of 6 values (1,6,7,18,20) and the HUNC is a numeric value denoting accuracy.
I have also tried pulling out just the data for a specific possource with a count command grouping on HUNC so my data looks like this

HUNC      COUNT
98              1256
100            95847
etc
this basically shows how many instances of a particular HUNC show up.

So what I am after is the 95th and 67th percentiles of the HUNC for all the various possource values, or a standard deviation curve showing the distribution but I am having trouble getting rapidminer to produce anything.

I am not trying to predict anything really, just trying to analyze and visualize existing datasets.
