Final answer:
The degree to which a sample resembles a parent population refers to sampling error.
Step-by-step explanation:
The degree to which a sample resembles a parent population refers to 1) Sampling error.
Sampling error is the natural variation that results from selecting a sample to represent a larger population. It decreases as the sample size increases, so selecting larger samples reduces sampling error. Sampling error is a measure of how accurately a statistic estimates a parameter and how well the sample represents the population.
