Answer:

Correct Answer:

Small sampling error

Explanation:

In every scientific study or poll, there is an expectation that, there would be a sampling error due to circumstances beyond ones control. This error is factored in when delivering the results of the poll (which is called margin of error in the result obtained). This small sampling error is one of the characteristics of a reliable scientific poll.
