Sample Size in Non Propbability

The probability  selection does not apply  to purposive  selection. The size  of the  non  probability samples  is selected  in a subjective manner. The researcher selects a size because  he feels  that the  size will be appropriate and the response  pattern will be  formed. In many studies the financial factor  is the single  factor  to decide the sample size  based on non  probability judgment. In  the quota sample some  criteria  are taken  into  account for  deciding  the sample  size. In  many  theories  of non  probability sampling the researcher consider the statistical significance sampling error method  of sample  selection   representation of  sampling and other factors. The  researcher should  base their  sampling  size in relation to  the statistical significance of the findings.
