User Defined Functions

[Guest]

I'm working on a project that involves two-way analysis of election results from the past 6 elections. To do the analysis I need to find the midmean of a data set. The midmean is the average of the values between the first quartile (25th percentile) and the third quartile (75th percentile). Is there any way to create a user defined function that carries out this process?
Also, if there is no way to create a user defined function, would it be possible to use a macro that would take an input of data, order it, find the quartiles and then find the mean of the values between the quartiles.
In addition, would it be easier to make user defined functions on Microsoft Access?

Thank you,

Use the TRIMMEAN function.
