Key Terms to Review (26)
Alternative Hypothesis: An alternative hypothesis is a statement that proposes a potential outcome or relationship that is contrary to the null hypothesis, suggesting that there is an effect or a difference in the context of a study. It plays a crucial role in statistical testing, allowing researchers to assess whether their observations can be attributed to chance or if they indicate a significant effect. This hypothesis serves as the basis for many research methods, guiding the analytical framework used to derive conclusions from data.
Conceptual Framework: A conceptual framework is a structured system of ideas and theories that guides research by outlining the key concepts, variables, and relationships that are relevant to a study. It helps to clarify the research problem and provides a foundation for interpreting findings, allowing researchers to connect their work to existing knowledge and identify gaps in the literature.
Construct validity: Construct validity refers to the extent to which a test or measurement accurately represents the theoretical concepts it aims to measure. It's crucial for ensuring that the inferences made based on the data collected are valid and reflect the underlying constructs, such as attitudes, behaviors, or traits. High construct validity involves both a clear theoretical framework and strong empirical evidence that the measurement aligns with that framework.
Critical Realism: Critical realism is a philosophical approach that combines a realist ontology with a constructivist epistemology. It acknowledges that there is a reality independent of our perceptions while also recognizing that our understanding of this reality is mediated by social and cultural contexts. This perspective emphasizes the importance of understanding the mechanisms that produce observable phenomena, allowing for a deeper analysis of social structures and power dynamics.
Falsifiability: Falsifiability is the principle that a statement or hypothesis must be able to be proven false to be considered scientific. This means that for any claim to be deemed credible, there must be a possible observation or experiment that could contradict it. This concept is essential in distinguishing scientific statements from non-scientific ones, reinforcing the importance of empirical testing and the pursuit of knowledge.
Falsification vs Verification: Falsification and verification are two contrasting concepts in the philosophy of science that address how we assess the validity of scientific theories. Verification involves confirming that a theory or hypothesis is true based on evidence, while falsification emphasizes the importance of disproving theories through experimentation. Both concepts play a crucial role in the post-positivist approach to knowledge, highlighting that knowledge is provisional and subject to revision.
Generalizability: Generalizability refers to the extent to which research findings can be applied beyond the specific context of a study to broader populations or settings. It is a crucial concept that ensures research results are relevant and can inform practices, policies, and further studies across different environments. Understanding generalizability helps researchers assess whether their conclusions can be reliably extended to other situations or groups, which is vital for the robustness of scientific knowledge.
Imre Lakatos: Imre Lakatos was a Hungarian philosopher of mathematics and science, known for his contributions to the philosophy of science, particularly through the development of the methodology of research programs. His work sought to reconcile the rigor of scientific theories with the complexities of real-world scientific practices, emphasizing that theories should be evaluated based on their ability to predict new phenomena rather than just their empirical adequacy. This approach connects with broader discussions on the evolution and validation of scientific theories within post-positivism.
Inductive vs. Deductive Reasoning: Inductive reasoning involves drawing general conclusions from specific observations, while deductive reasoning starts with general statements and reaches specific conclusions. These two forms of reasoning are crucial for understanding how knowledge is constructed and validated in research, especially within a post-positivist framework, which emphasizes the use of both approaches to build a more comprehensive understanding of phenomena.
Internal vs External Validity: Internal validity refers to the extent to which a study accurately establishes a cause-and-effect relationship between variables, free from confounding factors. External validity, on the other hand, assesses the generalizability of the study’s findings beyond the specific context or population studied. Understanding both types of validity is crucial in post-positivism, which emphasizes the importance of empirical evidence and acknowledges that all research is influenced by the context in which it occurs.
Karl Popper: Karl Popper was an influential philosopher of science known for his ideas on falsifiability and the demarcation problem, which distinguish scientific theories from non-scientific ones. His work emphasized that scientific knowledge is provisional and subject to revision based on empirical evidence, aligning with post-positivist views that recognize the complexity and variability of human understanding.
Mixed methods: Mixed methods refers to a research approach that combines both quantitative and qualitative techniques in order to gain a more comprehensive understanding of a research problem. This method allows researchers to leverage the strengths of both types of data, providing richer insights and validating findings through triangulation. It connects well with various philosophical frameworks and designs, enhancing the research process.
Null hypothesis: The null hypothesis is a statement that assumes there is no effect or no difference in a particular situation being studied, serving as the default position that a researcher tries to test against. It is a fundamental concept in statistical testing that helps researchers understand whether their findings can be attributed to chance or if there is a statistically significant effect present. By establishing a null hypothesis, researchers can apply various statistical methods to determine if there is enough evidence to reject it in favor of an alternative hypothesis.
Objectivity: Objectivity refers to the practice of perceiving and presenting information or data without being influenced by personal feelings, interpretations, or biases. It emphasizes neutrality and impartiality in research and analysis, allowing for conclusions that are based solely on observable phenomena and evidence. This concept is crucial for ensuring that research findings are credible and can be replicated, aligning with a broader commitment to truth and accuracy.
Over-reliance on empirical data: Over-reliance on empirical data refers to the excessive dependence on observable, measurable evidence in research, often at the expense of theoretical frameworks or qualitative insights. This tendency can lead to a narrow understanding of complex phenomena, as it may overlook the underlying meanings, contexts, and subjective experiences that cannot be easily quantified. It highlights the tension between quantitative approaches and the need for a more holistic perspective in understanding social realities.
Paul Feyerabend: Paul Feyerabend was a 20th-century philosopher of science known for his provocative ideas that challenged the traditional views of scientific methodology. He argued against the notion that science should adhere to a specific set of rules, promoting instead a more pluralistic and anarchistic approach to scientific inquiry, which he termed 'epistemological anarchism.' This perspective aligns with post-positivist thought by critiquing the objective, universal claims often associated with positivism and emphasizing the complex nature of knowledge and understanding.
Probabilistic Truth: Probabilistic truth refers to the understanding that knowledge claims can be evaluated based on their likelihood of being true, rather than asserting absolute certainty. This concept is particularly relevant in post-positivism, where researchers acknowledge that human perceptions and social phenomena are complex and often unpredictable, making it essential to consider probabilities rather than definitive truths.
Quantitative methods: Quantitative methods are research techniques that focus on quantifying relationships, behaviors, and phenomena using numerical data and statistical analysis. These methods often involve collecting data through surveys, experiments, or observations and then applying statistical techniques to analyze the results, allowing researchers to identify patterns and test hypotheses in a systematic way.
Quantitative vs. Qualitative: Quantitative and qualitative are two fundamental research approaches that differ primarily in their methodology and the type of data they produce. Quantitative research focuses on numerical data and statistical analysis to draw conclusions, while qualitative research emphasizes understanding the meaning and experiences behind human behavior, utilizing descriptive data and often involving interviews or observations. Both approaches offer unique insights and can complement each other in research.
Relativism: Relativism is the philosophical viewpoint that asserts that knowledge, truth, and morality are not absolute but are instead relative to the cultural, social, or individual contexts in which they exist. This perspective emphasizes that what may be true or morally acceptable in one context might not hold the same value in another, highlighting the importance of understanding diverse viewpoints. In various fields, this understanding can influence research methods and interpretations of data.
Reliability Measures: Reliability measures are statistical tools used to assess the consistency and stability of a research instrument or method over time and across different contexts. These measures help researchers ensure that their findings are dependable and can be replicated, which is crucial in the realm of post-positivism, where the objective is to uncover objective truths through systematic observation and analysis.
Replicability: Replicability refers to the ability of a study's findings to be consistently reproduced when the research is repeated under the same conditions. This concept is crucial for establishing the reliability and validity of research results, as it demonstrates that the findings are not merely due to chance or specific circumstances. In scientific inquiry, replicability serves as a cornerstone, reinforcing theories and methodologies across various research paradigms.
Scientific Realism: Scientific realism is a philosophical perspective asserting that the world described by science is real and exists independently of our perceptions or theories. This view holds that scientific theories can accurately describe the world and that unobservable entities posited by these theories, like electrons or black holes, are real. Scientific realism is closely tied to discussions about the nature of truth, knowledge, and the existence of an objective reality that science seeks to uncover.
Theoretical Framework: A theoretical framework is a foundational structure that guides research by providing a clear lens through which to analyze and interpret data. It connects theories, concepts, and variables, establishing a basis for understanding the phenomena being studied. This framework helps researchers formulate hypotheses, define their research questions, and select appropriate methodologies, ultimately shaping the overall direction of the research process.
Theory-ladenness: Theory-ladenness refers to the idea that observations and interpretations of data are influenced by existing theories, beliefs, or paradigms held by the observer. This means that what we see and how we understand it is not just a straightforward reflection of reality but is colored by our theoretical perspectives and prior knowledge. The concept highlights the subjective nature of scientific inquiry and the importance of critical thinking when evaluating evidence.
Thomas Kuhn: Thomas Kuhn was an American philosopher of science best known for his influential work on the structure of scientific revolutions. He introduced the idea that scientific progress is not linear but occurs through a series of paradigm shifts, which are fundamental changes in the basic concepts and experimental practices of a scientific discipline. This perspective connects to the way post-positivism challenges traditional notions of objectivity, how constructivism emphasizes the social context of knowledge, and various approaches to understanding epistemology.
