2014 VFBV Volunteer Survey - Data Integrity

The first survey in 2012 attracted responses from 805 CFA volunteers. Subsequent surveys using the same format have seen the survey result increase to 1,652 volunteer responses in 2014.


Given the high number of survey responses against the number of CFA volunteers, this represents a very robust sample of the views of CFA volunteers and can be treated as a ‘statistically significant’ response.


Sample size calculators indicate that 1,652 valid survey responses from a CFA volunteer ‘population’ of 60,000 provides a 95% level of confidence (getting the right answer 95 times out of 100) in the survey results, as representing the views of CFA volunteers.


Previous survey analysis for VFBV by Dawson McDonald demonstrated the statistical significance of the survey results against well-known Australian surveys. The VFBV survey results in 2013 achieved a 95% confidence level with a confidence interval of +/- 2.6%, considerably greater than many national surveys.

Survey respondents were given the option of responding anonymously or leaving their email address if they wished to be kept informed on progress with the survey results. This ensured that the survey respondents could provide their honest and open opinions in their written responses to the survey statements.


For security purposes, all online survey responses are entered into a securely encrypted electronic survey record system. All physical survey responses are also entered into the online system and destroyed once the data is recorded.
