I have a query that is arranged acorting to a number.

Name Money
Dan $150
Steve $60
Mike $20
Paul $10


for a lot more records of course. but i want to be able to decide the
person who is the lowest one in each percent as in if i wanted
to produce the following output

Percentile Money
90% $150
80% $150
70% $60
60% $60
50% $60
40% $20
30% $20
20% $10
10% $10

is there an easy way to produce this?


Thanks

Partition() does almost the inverse of what (I think) the OP wants -
it rerurns the number of records with values in a specified range - he
wants the border value of a specified proportion of records.

There is no native Access function which returns percentiles,
quartiles, etc. I have written (and published here previously) a Class
which does the hard work of this, though the OP would need to to write
a bit of VBA code to make use of it for his specific purposes. I will
give another pointer to the package, if he likes.

Hi Mark,

Look up the PARTITION() function in the OLH.

There's one posted at Dev Ashish's site, too:

Another option would be to download the trial version of FMS's "Total
Access Statistics," which calculates quartiles, deciles, and centiles
from the 1th to the 99th %ile. Note that the trial version works on
tables only, not on queries.
