Why? There are 2 main sources of error in inexpensive crystal oscillators. The first is the initial manufacturing error. I'd expect crystals made from the same batch to have similar errors. If you want a large population, you are going to get most/many of them from similar batches. The other is temperature. I'd expect that oscillators of a specific design to have similar temperature dependencies. Some vendors even include a graph in their app-notes. It might be interesting to collect oscillators from different vendors and batches and see what sort of spread you end up with. -- These are my opinions, not necessarily my employer's.
