Sociology can actually be defined as the study of the behavior of human beings in the society (Landis, 1999). It is the study of various social human activities as well as other collective social behaviors. Sociology is used to measure the social world through its ability to study the behavior of human beings from a collective aspect. In this way, sociology measures the social world by determining all group activities starting with social activities, economic activities, religious practices as well as political behavior. Its ability to study and analyze social aspects such as deviant behaviors, changes in social behavior, bureaucracy and family issues gives it an upper hand in measuring the social world. Other social aspects studied and analyzed by sociology include the opinion of the public, social mobility, drug abuse, crime, child abuse and other family specific issues (divorce). Sociology is also used in determination of various social laws used to guide and govern varying modes of social conduct and human behaviors in diversified social contexts (Landis, 1999). This process is not easy at all since it requires a high level of understanding of the social world including human behaviors, cultural conduct, religious beliefs and many other social aspects as mentioned. The process may sometimes require social professional skills especially when determining complex aspects of the social world such as ethnicity, wars and migration. The process proves to be even much cumbersome following varying individual/community responses and diversified attitude. It is actually hard to make projections of social aspects or predict social outcomes in a social setting and this makes the process of measuring the social world hard (Babbie, 2003).
Sociology is practiced in situations such as sports, schooling, religious practices, cultural practices and other social events. In these situations, interaction/socialization is important in ensuring that the members are free with one another (reduced anxiety, curiosity and fear). When such activities are scheduled, sociology becomes very vital to enhance understanding amongst the attendants and at the same time embrace peace. Sociology is practiced when the participating groups, members or individuals need to make collaboration for purposes of achieving a common goal (Landis, 1999). In this case, the members have to consolidate their social standings and interact with other to achieve the desired outcomes. Sociology is also used when there is need to carry out sociological research or if there is need for collection of social data by application of quantitative and qualitative social research approaches. One of the major reasons why sociology is practiced is because it is the only sure way of dealing with human dynamism from a social perspective. It enables researcher to understand human beings and how they relate to their surrounding/society. Sociology is practiced by means of exchange of social aspects such as social norms, culture, religious practices, intermarriages and group interactions (Babbie, 2003).
To the social sciences, sociology enables collection, analysis and application of social data in varying social contexts. Through sociological methods of collection of data (quantitative and qualitative methods), it enhances the work and career of sociologists in accomplishing assigned tasks and responsibilities in the social world. It also enables social researchers to write and publish original peer reviewed journals and articles. This helps in promotion of the theoretical understanding of social aspects and enhances reporting of empirical social research concerning a wide range of sociological topics. This is what actually qualifies sociology as an applied science (Landis, 1999).
