Appendix 2: Research methodology

A2.1   Data collection

A telephone survey was conducted with people aged 15 years or over, who live in Auckland, Hamilton, Wellington, Christchurch or Dunedin, and have used a taxi within the last three months.

All telephone interviews were conducted by fully trained and experienced interviewers, using the Computer Assisted Telephone Interviewing (CATI) process between 21 May and 10 June 2008.

A2.2   Sample and response rate

The total sample was (n=810), resulting in an 8% response rate (see Chart 10 for details of contact distribution). At the 95% confidence interval, a sample of (n=800) has a margin of error of 3.5%, a sample of (n=400) has a margin of error of 4.9%, and a sample of (n=100) has a margin of error of 9.8%.
