Dare I ask why you want to dichotomize?  More often than not, it's a bad idea:  You throw away information and lose power.  There are several good articles on the topic, including this very readable one by Dave Streiner.

Dear Listserv,

I used Multiple Imputation in SPSS 17 MVA.
Now, I want to dichotomize my DVs based on their median value.
However, in frequencies output, I did not see median for POOLED dataset.
How can I get it?

The next step is Logistic Regression.
Some tables of Logistic Regression output.... I did not get the result of pooled dataset.
Those tables are...
Omnibus tests of model coefficients, Model summary, and Classification table.
Is there any way to get the results of pooled dataset on these tables?
If it's not.... how can I report my results?
