Final answer:
Generalizing the results of a study with a small sample to other subjects is dependent upon the sampling method used. Researchers use random samples to represent the population.
Step-by-step explanation:
Generalizing the results of a study with a small sample to other subjects is dependent upon the sampling method used. Researchers use samples to represent the population because it is not practical to measure the entire population in a study. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample.
