What is non-random selection?
A non-random selection is one in which all of the people do not have equal chance of being included in the sample.

What is the purpose of blank samples?
Blank samples are used to establish a baseline measurement of background contamination in an analysis. By analyzing a blank sample containing no target analytes, researchers can identify and account for any background signals or contamination that may affect the accuracy of their results.
