ENTFACT Procedure for Selecting Random Sites for Sampling | Download PDF. by Doug Johnson, Extension Entomologist University of Kentucky College. Criteria Of Selecting A Sampling Procedure take a random sample in a relatively easier way without taking the trouble of enlisting all possible samples on paper-slips as explained above. We can illustrate the procedure by an example.
