Why is experimental design is the strongest design for testing cause and effect relationships?
Wiki User
∙ 6y ago
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?
Types of education research include experimental research, correlational research, qualitative research, and mixed-methods research. Experimental research involves manipulating variables to study cause-and-effect relationships. Correlational research examines relationships between variables without manipulating them. Qualitative research focuses on understanding complex phenomena through in-depth exploration of individuals' perspectives, experiences, and behaviors. Mixed-methods research combines both qualitative and quantitative approaches to gain a deeper understanding of educational phenomena.
What does conceptual mean?
Conceptual refers to something related to ideas or concepts rather than tangible objects. It typically involves abstract thinking or understanding of principles, theories, or relationships without direct physical representation.
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.
What is the vocabula word for testing a hypothesis by using carefully controlled steps?

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.

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.

What is a quasi experimental design?
A quasi-experimental design is a design that resembles and experimental design but does not have the key ingredient of random assignment. They involve selecting groups that are used to test a variable but with no random pre-selection process.
