[AccessD] Trimmean Function in Excel - How to in Access

Well I'll try. :-)

Say you have exactly 100 records, so your goal is to get the middle 80
records in your result.

The first query returns the "top 90%" of the data, so it should be sorted in
ascending order so that the query will return records 1 to 90.

Then you use that query as the input to the second query. The second query
sorts in descending order (90, 89, 88...) and its Top property is set to
88%, which should give you a result of records 90 to 11.  Why 88% ? Well the
first query returns 90% of the original records and you need to lose the
bottom 10 records which is 10/90% which is roughly 11.11%. By trying it out,
if the second query returns 89% or records you get 81 out of the original
100, but if you set it to 88% you will get 80 records.
