Group is defined as a collection of people who interact based on shared expectations of one another's behavior. There are two main types of groups - primary groups characterized by close personal ties, like families, and secondary groups with fewer emotional ties like workplaces. Groups can also be defined as in-groups that one identifies with or out-groups that are viewed more neutrally or negatively. Reference groups provide norms and allow for social comparison. The main social institutions that meet a society's basic needs are family, education, religion, economy, and politics.

7. Different types of groups

8. Primary group
Are characterized by warm personal ties among members
(Hess et al., 1996)
The family is the first and ideal example of a primary
group: it gives its members a sense of being special and its
survival depends on their shared identity and concern for
one onother ( Stone, 1998 in Hess et al., 1996)

9. Secondary groups are characterized by few emotional ties
among members and limited interactions involving only a
part of the self.
Examples include most classrooms, offices, and voluntary
associations such as PTAs or church congregations (Lindsey
and Beach, 2012)

10. Secondary groups
-either large or small, although they are mostly large. Some small
secondary groups may become increasingly primary over time as the
members get to know each other better.
Moreover, primary groups are often embedded in or emerge from
secondary groups.
In addition to the distinction between primary and secondary groups,
sociologists also call attention to how people view their own and other
groups. William Graham Sumner (1906 in Sullivan, 1995) coined the
terms “in-group” and “out-group” to distinguish between groups that
generate quite different feelings.

11. In-group
Is one that we feel positively toward and identify
with, and that produces a sense of loyalty or “we”
feeling.

12. Out-group
Are those to which we do not belong and that we
view in a neutral or possibly hostile fashion. We
view out-groups as “they”, as different from and
less desirable than ourselves.

13. Reference group
Are composed of people we look to in order to evaluate
our own behavior. They serve two closely related but
distinct functions:
• Normative function
• Comparative functions

14. Normative function
- Providing guidance concerning how to act.
Comparative function
- We can assess ourselves in relations to others.
When these functions are provided by a single person,
we call that individual a Role Model.

15. Institutions A social Institution is a set of widely shared
beliefs, norms, or procedures necessary for
meeting the basic needs of society.
The most important institutions are:
• Family
• Education
• Religion
• Economy
• Politics

16. According to David F. Aberle et al.,(2005) have identified five
major tasks that a society or relatively permanent group must
accomplish if it is to survive:
Replacing personnel
Teaching new recruits
Producing and distributing goods
and services
Preserving order
Providing and maintaining a sense of purpose
