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.
