Yesterday on All Things Considered (NPR), Quil Lawrence did a lengthy segment on a new study

Dr. Rasooly says the survey's margin of error is pretty big, but he has no doubt health is much better now than 10 years ago. It's not about knowing the exact number, says Ken Yamashita, USAID mission director in Afghanistan.
Lawrence is a reporter. So why is it that he never told us the margin of error?
