Explanation:

Sampling bias or coverage error is the term of sampling in social studies. Selection bias occurs when the researcher collects data from the population and that data has no meaning and value. This happened because the participants who are selected into the sampling are not selected fairly for both the groups. In the experimental group and control group, both the groups are representative of the sampling or general population. Theses groups represented each other as well. Both groups are equal. No one group represents higher than another group because it will make the findings distorted.

the anti federalists was a movement that was opposed to the creation of a us federal government. although they were not as organized as the federalists, they also had a large group of leaders, especially in state politics.

the statement "now, in a large extended country, it is impossible to have a representation, possessing the sentiments, and of integrity, to declare the minds of the people” represents the concerns of the anti federalists.

they strongly believed that the federalists were representing the interests of aristocratic elements of society at the expense of the majority of ordinary people, who lived in a rural society.

their fear for the creation of a strong federal government and the president’s power of veto in their opinion would create a tyrannical rule that would dominate the people. they defended the importance of restraining the government’s power towards people at any cost.
