Types of Research - Pure and Applied, Difference with Social Research
Definition of Pure Research
Pure research, also known as basic research, is aimed at gaining a deeper understanding of fundamental principles without any immediate application in mind. This type of research focuses on theoretical exploration and contributes to the broader knowledge base.
Definition of Applied Research
Applied research seeks to address specific, practical issues and often aims to develop solutions or policy recommendations. It is characterized by a focus on real-world applications and is typically more targeted than pure research.
Differences Between Pure and Applied Research
The primary difference lies in their goals; pure research focuses on expanding theoretical knowledge, while applied research targets solving practical problems. Additionally, pure research often results in new theories, while applied research modifies and applies existing theories.
Overview of Social Research
Social research is a systematic investigation that aims to better understand social phenomena and human behavior. It encompasses a variety of methodologies and can be either qualitative or quantitative in nature.
Comparison of Social Research with Pure and Applied Research
Social research can fall into both categories. It can be pure when it explores theoretical aspects of social issues without immediate practical applicability. Conversely, social research is applied when it addresses specific social problems and develops interventions or policies.
Importance of Understanding These Types in Social Work
In the context of social work, distinguishing between pure and applied research helps practitioners choose appropriate strategies for addressing social issues. Understanding social research methodologies enhances the ability to inform practice and improve outcomes for individuals and communities.

The scientific method is a systematic approach to inquiry that involves observation, hypothesis formulation, experimentation, and analysis. In social work research, the scientific method helps practitioners understand complex social phenomena, assess interventions, and improve practice.
Need and Importance of Evidence-Based Practice
Evidence-based practice (EBP) integrates the best available research, clinical expertise, and client values to inform decision-making. EBP enhances the effectiveness of social work interventions, ensures accountability, and promotes better outcomes for clients.
Ethical Issues in Social Work Research
Ethical issues in social work research include informed consent, confidentiality, and the potential for harm to participants. Researchers must ensure that their work adheres to ethical standards that respect the dignity and rights of individuals.
Formation of Ethics Committee
Ethics committees in social work are essential for overseeing research practices, ensuring compliance with ethical guidelines, and addressing ethical dilemmas. They review research proposals, facilitate ethical training, and promote a culture of ethical awareness within organizations.
Basic Elements of Scientific method - Concept, Variable, Facts and Theory, Cause-Effect relationship
Basic Elements of Scientific Method
A concept is an abstract idea or a general notion that represents something.
Concepts serve as the building blocks of scientific theories and help in understanding phenomena.
A variable is any factor, trait, or condition that can exist in differing amounts or types.
The variable that is manipulated or controlled in an experiment.
The variable that is measured or observed in response to changes in the independent variable.
Understanding variables is crucial for formulating hypotheses and conducting experiments.
Facts are observations that can be repeatedly confirmed and are accepted as true.
Facts form the foundation of scientific knowledge and provide the evidence needed for forming theories.
A theory is a well-substantiated explanation of an aspect of the natural world based on a body of evidence.
Unlike facts, theories provide a broader context and explanation for scientific observations.
A cause-effect relationship indicates how one event leads to another.
Understanding these relationships is vital for making predictions and determining the validity of hypotheses.

Research Methodology - Sampling Concept, Techniques, Probability and Non-Probability Sampling
Introduction to Sampling
Sampling is a technique used in research to select a portion of the population for analysis. It allows researchers to draw conclusions about a larger group without surveying every individual.
Importance of Sampling in Social Work Research
In social work research, sampling helps in obtaining reliable data while managing time and resources. It enables researchers to study diverse populations and their needs effectively.
Types of Sampling
Sampling can be classified into two main types: probability sampling and non-probability sampling.
Probability Sampling
Probability sampling involves random selection, allowing each member of the population an equal chance of being chosen. This method enhances the representativeness of the sample.
Techniques of Probability Sampling
Common techniques include simple random sampling, stratified sampling, systematic sampling, and cluster sampling. Each technique has specific applications in social work research.
Non-Probability Sampling
Non-probability sampling does not involve random selection. This means not all members have a chance to be included in the sample, which may lead to biases.
Techniques of Non-Probability Sampling
Techniques include convenience sampling, judgmental sampling, quota sampling, and snowball sampling. These methods are often easier and quicker but may compromise the generalizability of findings.
Comparison of Probability and Non-Probability Sampling
Probability sampling is generally preferred for its statistical validity, while non-probability sampling is suitable for exploratory research where randomness is not crucial.
Conclusion
Understanding sampling techniques is essential for social work researchers to gather accurate data and improve the effectiveness of their interventions.
