... This is a special type of purposive sample. Here the researcher takes explicit steps to obtain a sample that is similar to the population on some “pre-specified” controlled characteristics. e.g., a interviewer may be instructed to select half of the interviewees from people 30 years of age and older ...

... If a sample size of n is desired from a population containing N elements, we might sample one element for every N/n elements in the population. We randomly select one of the first N/n elements from the population list. We then select every N/nth element that follows in the population list. This meth ...
