how to use statistics to extract information
Goastros,
Up to now, I heard on this forum that the I-485 processing is quite random. In fact, randomness is just a idealized concept.
In fact, our samples are not chosen systematically and the samples are not large enough.
If we have few volunteers who run Excel Macro regularly, we will have some ideas ( or at least we can prove the randomness).
After the first run we don't have to run so long, taking advantage of the ModifiedScan.
At the moment, I have the following assumptions:
1. In 2003, the I-485 approvals have slown down.
2. The cases of 2002 were processed mostly in 2002 because, the cases of 2001 were not processed for some reasons.
and much more. We definitely can discuss more after we collect enough data.
