The great compromise settled a dispute between which two groups?

The Great Compromise settled a dispute between large states and small states, that had discrepances over the organization of the federal legislature.

Explanation:

The Great Compromise of 1787 unified the Virginia Plan, that favored population-based representation, and the New Jersey Plan, which listed each state as an equal.  

It established a bicameral system: one chamber in favor of the Virginia Plan, based on the population of the States, and the other in accordance with the New Jersey Plan, by which all States voted in equality.

This was an important issue in the new United States. The small States, with a small population, wanted their voices to be heard in the US government, as well as those of large states with a large population, such as Virginia or New York. With its plan, Virginia wanted to have greater representation because a large percentage of the US population was in that state. In this way they would have control over what happened in the entire United States.
