METHODOLOGY
Sample
Conducted nationally among 526 parents /guardians of children aged 5 - 15 years.
Respondents were selected via a random sample process which included:
- a quota being set for each capital city and non-capital city area, and within each of these areas, a quota being set for groups of statistical divisions or subdivisions;
- random selection of household telephone numbers using random digit dialling (RDD);
- random selection of an individual in each household by a "last birthday" screening question.
Interviewing
Conducted by telephone over the period of 15 - 17 & 22 - 24 August, 2008, by fully trained and personally briefed interviewers.
To ensure the sample included those people who tend to spend a lot of time away from home, a system of call backs and appointments was incorporated.
Weighting
To reflect the population distribution, results were post-weighted to Australian Bureau of Statistics data on age, highest level of schooling completed, sex and area.
