Why is experimental design is the strongest design for testing cause and effect relationships?
Experimental design is considered the strongest for testing cause and effect relationships because it allows researchers to manipulate independent variables to observe their effect on dependent variables while controlling for extraneous factors. This control enables researchers to establish a direct causal relationship between the variables being studied. By randomly assigning participants to different experimental conditions, experimental design helps to minimize bias and increase the internal validity of the study findings.

Why quasi experimental design are high in external validity?
Quasi-experimental designs involve studying real-world settings and conditions, which increases the generalizability of the findings to other similar contexts. The use of diverse samples and settings in quasi-experimental designs enhances the external validity of the results by allowing researchers to draw conclusions that can be applied to a broader population. Additionally, quasi-experimental designs often involve manipulating independent variables in natural settings, making it easier to extrapolate the findings to real-life situations.
What are the five stages in program development and its definition?
Analysis: Gather and analyze requirements for the program. Design: Plan the structure and components of the program. Implementation: Write the actual code for the program based on the design. Testing: Verify that the program functions as intended and fix any bugs. Maintenance: Update and maintain the program to ensure continued functionality and relevance.
How is educational research classified?
Educational research can be classified into different categories such as quantitative research, qualitative research, mixed methods research, action research, and experimental research. These classifications are based on the research methods, approaches, and design used to answer research questions in the field of education.
Types of education research?
Generally there are three types of research design: quantitative design, qualitative design, and mixed methods design.Quantitative Research Design:Measured and express in terms of quantity. Expression of a property or quantity in numerical terms. Quantitative Research Design helps in precise measurement, knowing trends or changes overtime, comparing trends.Qualitative Research Design:Involves quality or kind, helps in having insight into problem or cases.Mixed Research Design: The type of research in which a research or team of researchers combines elements of qualitative and quantitative research approaches (e.g., use of qualitative and quantitative viewpoints, data collections, analysis, inference techniques) for the broad purposes of breadth and depth of understanding and corroboration.
What is the difference between theory driven and data driven research?
Theory-driven research is guided by existing theories and hypotheses, while data-driven research relies on analyzing data to generate insights and patterns without predefined theories. In theory-driven research, the focus is on testing and confirming existing theories, whereas data-driven research focuses on exploring and discovering patterns in the data to derive new insights.
What permits inferences about cause and effect relationships?
experimental design
Where can one find out the results of Design of Experiments testing?
One can find out the results of "Design of Experiments" (DOE) testing (also known as experimental design) at the official sites of companies that offer such services.
Why is experimental design a key factor in science inquiry?
The experimental design is always a key factor in the science inquiry. The experimental design shows the methods that lead to the science.
Can you give you a sentence using experimental design?
The next car show will have an example of our experimental design.
What are the advantages and disadvantages of ex post facto research?
advantages:its ideal for testing demographic variables which cannot be manipulated. like a non-experimental design it doesn't require much to collect data, but just merely shows effects of a presence or absence of an Independent variable on a Dependent variable.disadvantages:it cannot acquire as much data as an experimental design, the levels of the "IV" are already established. If anything it tries to be an experimental design but it cannot.

How is a quasi-experimental design different from a pure experimental design?
pure -absolute control Quasi -have some control
Write short note on experimental reserach design?
Experimental research design involves manipulating one or more variables in a controlled setting to observe the effect on the dependent variable. It allows researchers to establish cause-and-effect relationships by controlling for potential confounding variables. This design is characterized by random assignment of participants to different conditions and the use of control groups to minimize bias and increase the internal validity of the study.
What is the vocabula word for testing a hypothesis by using carefully controlled steps?
The word is "experimentation." Experimentation involves testing a hypothesis by conducting carefully controlled steps or procedures to observe the outcomes and draw conclusions.
