The 25th annual Computerworld Salary Survey was administered via the Internet. Responses from both Computerworld print subscribers and visitors to Computerworld.com were included in the survey results.
Starting on Oct. 5, 2010, the following methods were used to invite participants to take the survey:
- Visitors to Computerworld.com were presented with a pop-up box inviting them to participate in the survey (with a frequency cap of once per user). Visitors were given the option of bypassing the survey to get to their intended destinations.
- Links to the survey were included in various Computerworld e-mail newsletters.
- Computerworld subscribers employed in IT job functions were sent an e-mail message from SalarySurvey@computerworld.com inviting them to participate in the survey. For tracking purposes, each participant received a unique address to gain access to the questionnaire. Subscribers could either click on the address to gain access to the questionnaire or enter the address into a Web browser. A survey couldn't be submitted more than once from each unique address.
- Cookies were used to ensure that there was no duplication of responses between or within the various sample groups. In addition, duplicate responses from the same e-mail address were removed.
The survey ended Dec. 20, 2010. A total of 5,343 people responded to the survey. Of those respondents, 4,852 were employed full- or part-time and were eligible to complete the entire survey. At the 95% confidence level, the margin of error for this sample size is 1.4 percentage points.
