How to design a research project

The distinction between qualitative and quantitative research is commonly made.

Quantitative research is sometimes referred to as statistical or sometimes (somewhat sloppily) as empirical research.

Qualitative research is sometimes referred to as the sociological approach to research.

Elsewhere the distinction is often made between certain research methods as either being Qualitative or Quantitative.

For example Interviewing, Participant Observation and Documentary Analysis are often referred to as Qualitative research methods.

The use of Surveys and Statistical data is referred to as Quantitative.

These distinctions do have a fair degree of truth to them. However as we will see later they do not hold true in all cases. What are commonly thought of as used in purely Qualitative research can be part of Quantitative research programmes and vice versa.

In this lecture we are going to look at this distinction between qualitative and quantitative research. After looking at brief definitions of each we are going to look at what the goals of social research are. This will allow us to reflect on how both qualitative and quantitative research strategies can be employed to achieve those goals.

Definitions

"Qualitative Research is a basic strategy of social research that usually involves in-depth examination of a relatively small number of cases. Cases are examined intensively with techniques designed to facilitate the clarification of theoretical concepts and empirical categories." (CC Ragin, 1994, p190)

"Quantitative Research is a basic strategy of social research that usually involves analysis of patterns of covariation across a number of cases. This approach focuses on variables and relationships among variables in an effort to identify general patterns of covariation." (CC Ragin, 1994, p190)

Each can make a contribution to the study of society.

The best way of approaching their relative strengths and weaknesses is through looking at what are the goals of social research.

7 Goals of Social Research (from CC Ragin)

- Identifying General Patterns and Relationships

Thinking back to last week we discussed how one of the key features science is the identification of General Patterns and Relationships. Those that see social research as a true science often see this as the Primary Goal of research.

Knowledge of general patterns and causes of social phenomena are often valued because they can help us address social problems or act to guide policy.

For example, if research were to suggest that poor attendance at school were a cause of crime then that would give us a possible approach to tackling crime.

Social researchers may believe that discovering general relationships is best done through the examination of many cases. THe reasoning being that certain cases may be atypical but that by looking at many cases we can identify generalities.

2 - Testing and Refining Theories

General patterns are especially relevant to social theory. The implications of theories are tested and refined or discarded. Typically this is done according to a general plan of scientific method.

Hypotheses are derived from theories and their implications and then tested with data that bear directly on the hypotheses.

In theory we abandon a theory if it is falsified by an observation.

In practice a single piece of counter evidence or a single unsupported hypothesis usually does not result in abandoning a theory. Rather unsupported theories gradually fade from current thinking or are refined.

3 - Making Predictions

Social researchers use accumulated social scientific knowledge to make predictions about the future and other novel situations.

Predictions can be made from two types of knowledge.

Firstly the use of Historical Knowledge.

e.g. The Stock Market Crash of 1920 and ensuing Great Depression has motivated our economic and political elites to moderate the violent swings of market oriented economic life.

Secondly the use of General Patterns.

For example we know that certain types of criminal activity - drug dealing - increase when legitimate economic opportunities decrease. We can use this knowledge to predict future crime rates based on economic predictions.

Predicting rates - crime, unemployment etc - is much easier than predicitng specific events such as the fall of the Berlin Wall and suchlike. At best social scientists are making broad predictions about trends.

4- Interpreting Culturally or Historically Significant Phenomena.

Certain atypical events are interesting because of the role they played in establishing the current situation. For example the US Civil War has an impact on current power relations. There may be competition between different interpretations of events to become the accepted interpretation.

In fact often there is no single accepted "correct" interpretation of an event and different analyses are seen to bring different understandings.

Research which seeks to explain particular events often addresses issues related to the consciousness of the actors involved - whereas research which sseks to establish generalisations often does not.

In other words the intentions of particular people involved in events are often addressed in event specific research.

5 - Exploring Diversity

The goal of exploring and comprehending social diversity surrounding us.

This is related to the search for general patterns but instead seeks to understand the deviations from those patterns.

Ragin argues this goal of social science is about the study of unusual social practices and phenomena.

6 - Giving Voice

Research which seeks to tell the story of, raise understanding of or give a voice to a group in society.

The researcher often has to unlearn or disregard established theories to present the subjects' interpretation of the world.

There is a debate as to whether such research is simply a type of advocacy for a given group or way of life. Even if it is it may be valid in offering an alternative conception to the mainstream.

7- Advancing New Theories

Theory testing (goal 2) is usually primarily deductive.

By contrast Theory advancing research is usually described as inductive.

The classic conception of such research is of in depth case studies leading to an understanding of a social phenomenon from which new theories, ideas or concepts are generated.

So whereas for deductive research the theory comes first and observation is collected to test the theory.

For inductive theory advancing research - first we collect data or investigate a subject and formulate theory from that.

It is often not possible or desirable to address all or most of these goals tegether in one piece of research.

For example the different stage of data collection creates difficulties if we attempt to both test and develop theory in the same piece of research.
