Paul M. Davis:
“Data is” or “data are”? It’s the type of sticky linguistic thicket that invites vociferous debate. […] I generally err towards “data are”, if for no other reason than to avoid angry email from data and/or grammar geeks.
Make sure you don’t miss the link to Simon Rogers’s post on Datablog looking into this same topic.
As for myself and this blog, I’ve made the (un)educated decision a while back to go with “data is” (based only on the fact that it sounds better).
