The early consensus estimate among economists was for a growth of 250,000 new jobs. However, a sample of 20 economists taken Thursday afternoon provided a sample mean of 266,000 with a sample standard deviation of 24,000 Financial analysts often call such a sample mean, based on late-breaking news, the whisper number.
