Answer:

Sampling error

Explanation:

Dr. Sun is bound to have sampling error affect the result of his study. This is because sampling error in research is said to occur when a researcher just takes a random sample, usually a small number of the population of the study and chooses to study this sample rather than observing every subject that makes up the population.
