When a random sample is not representative of the population as a whole, we refer to it as sampling error. What can you do to reduce your risk of sampling error? In other words, what can you change about how you sample to be more confident that it is representative of the entire population? Increase the size of the random sample (e.g., catch more ducks) Collect a non-random sample of the population (e.g., catch only small or only large ducks) Decrease the size of the random sample (e.g., catch fewer ducks)
