Private interest groups are those with personal stakes on an issue. Public interest groups are those groups that advance the concerns of the public at large.
As noted by Thomas Dewey, there is no clear dividing line between the public and private interests. In practise, private interest refers to the acts of individuals to meet their own ends, so they do not tend to form 'groups' insofar as private interests are usually not shared. Most private interest groups are called special interests which typically form from aggregations of individuals with the same goal, such as corporations or unions. Public interest groups contend to be groups that represent the broader interest of society itself even though such groups often do not comprise much of it.

Interest Groups
The difference is that a political party is part of how a politician is identified and interest groups are groups that focus specifically on certain issues. Depending on the issue interest groups tend to support a political party. For instance the NRA which is for less strict gun control laws associates themselves with the Republican Party. An interest group that is supportive of equal rights for all Americans would associate with the Democrat Party.
The difference between private and public is that private is where their are certain people in groups, like when there are private schools for boys and girls. Public is when everyone can be involved and it doesn't matter who joins and if you want to join them or not!
The family group live together, take meals together and share the same home. The non-related groups are people brought together by common interest.
A research group that looks to find solutions to problems or to create them is generally speaking not political. When a special interest group uses the work of research groups to push for legislation, that is the basic difference between the two groups. Now, with that said, there are research groups that then use their research to lobby for legislation that supports their group's goals.
