Sampling Error

Every sample drawn from a population has a known sampling error associated with it. This value is the amount the survey responses differ from true population values. In this case, this includes the difference between the sample collected from ASPS members and all ASPS members nationwide.

The maximmum standard range of a sample of 607 is +/- 4.0 percentage points at a 95% confidence level. An error range of +/- 4 percentage points means that if 100 different samples of 607 physicians each were randomly drawn from the ASPS membership population, 95 times out of 100 the total results obtained would vary no more than +/- 4.0 percentage points from the results that would be obtained if the enitre ASPS membership population was surveyed.

Expected Error Ranges for a Market Sample of 607 Respondents*
Percent of sample: 10% 20% 30% 40% 50% 60% 70% 80% 90%
Error ranges: +/- 2.4 +/- 3.2 +/- 3.6 +/- 3.9 +/- 4.0 +/- 3.9 +/- 3.6 +/- 3.2 +/- 2.4
* At a 95% confidence level.
