摘要：The current paper presents an effective
sampling method accessible to health promotion programs? evaluation fitted to
get rich information about issues of central importance to the purpose of the
assessment. Method. The data collection procedure is rooted in a maximum
variation sampling. The sample design is based on t he principle of maximum diversity, which is an extension
of the statistical principle of regression towards the mean based
on which instead of seeking representativeness through equal probability, it is
sought by including a broad range of extremes. Results . The desirable
sample size for our evaluation is
264 respondents. Based on this value we established the key dimensions of
diversity which enable us to set up the entire sampling procedure.
Conclusions . Maximum variation sampling allows that against scarcity of
data to achieve considerable results which
can be more representative than those gained through a random sample.
